Introduction   

For many years, plants were used as a way for survival, healing, and even spiritual connection. Prior to the development of modern medicine, the indigenous cultures adapted deep rooted generational relationships with the natural world. Using medicinal and ceremonial plants to help restore and balance the body, mind and spirit. A few of the most culturally significant plants are peyote (Lophophora williamsii), white sage (Salvia apiana), and the various tobacco species (Nicotiana species). These significant plants are not only used for their beneficial medicinal effects, but also for their spiritual and ceremonial importance. In recent years, there has been an dramatic increase in scientific research towards photochemical, plant-specific biotechnology and ethnobotany, which has emphasized the interest in these species, connecting the traditional indigenous knowledge with ongoing research.  

Peyote has been used for many years as a sacred sacrament in many indigenous communities in order to help individuals heal, and also as a spiritual aid. The psychoactive compound mescaline, which is found in peyote, has become a subject of interest to scientists for its potential role in helping mental health. Additionally, the white sage species is commonly an important part of the cleansing rituals that are a part of many indigenous communities. White sage is also used for traditional medicine, spiritual cleaning and healing. The tobacco species, which is commonly seen misused in our everyday lives for various commercial products are also used as a sacred plant in many indigenous ceremonies, which are conducted to connect to the spiritual world. Tobacco has been demonstrating the potential in modern science advancement, by potentially being able to produce vaccines and also help reduce the amount of pollutants in the environment.   

Although this species has a long history of being respectfully used by the indigenous communities, the species now faces a risk of over harvesting, commercialization and even habitat loss. The growing demand globally for peyote, the increase in illegal harvesting of white sage and the commercial demand for tobacco production have caused a serious risk for these culturally significant plants. Currently, advancements in micropropagation, phytoremediation and pharmaceutical studies have garnered more attention on the medicinal and environmental impact these species have on the world.  

This paper will help explore the propagation and cultivation, medicinal effects, botany and the spiritual and ceremonial importance of peyote, white sage and tobacco. It will also further explore the plant’s current health uses and the conservation challenges the species is facing. The paper will highlight how traditional indigenous knowledge is used with modern research while still being able to respect and value the cultural origins, while supporting scientific progression. Honouring both the scientific and spiritual aspects of these species can ensure that they stay present for future generations as a source of healing and spiritual connection.   

Peyote: Lophophora williamsii   

I. Botany

Peyote (Lophophora williamsii) is a small acaulescent cactus native to the Chihuahua Desert, to this day it grows wild solely in its native range throughout Mexico and Texas. It is typically found growing in shallow soils in arid regions, as such it can tolerate poor soils and drought-like conditions (North Carolina State University Extension [NCSUE], n.d.). The peyote cactus thrives when grown in well drained alkaline soil, provided with indirect sunlight or partial shade and when the climate conditions are dry and hot. The matured cactus is light green in colour and may produce tufts of yellow fibre, they can grow up to 12.5 cm wide and 7.5 cm tall. Despite its relatively small mature size, it is a slow-growing cactus that takes from 10 to 30 years to reach maturity and produce flowers, unlike many other species of cacti, it does not produce any spines (NCSUE, n.d.).    

While other cacti rely on spines to deter predation, peyote accomplishes this by producing chemical deterrents, most notably, the psychedelic compound mescaline, which is a phenethylamine protoalkaloid (Watkins et al., 2023). The highest concentration of mescaline in the cactus is contained in the apex of the stem during the flowering period; the rest of the plant does contain mescaline but at a much lower concentration (Kleffins et al., 2023 & NCSUE, n.d.). The peyote flowers are generally light pink and bloom during the summer months, once pollinated a small berry begins to develop that takes up to a full year to mature, neither the flower nor fruit contain significant amounts of mescaline. Once harvested the stem apexes are commonly referred to as mescaline buttons and represent the plant product used for medicinal and ceremonial purposes (NCSUE, n.d.).    

II. Propagation & Cultivation   

Peyote can naturally reproduce sexually by dispersing seeds or asexually by undergoing lateral branching and with it, the formation of new plants. Like many other species of cacti, peyote can be vegetatively propagated, most commonly by dividing offshoots, planting stem cuttings or grafting cuttings onto other plants (NCSUE, n.d.). As peyote has a very slow rate of growth and a limited native range, overharvesting is a major concern for the long-term survival of the species (Ermakova et al., 2021). As early as the 1970s it was suggested that peyote was threatened as a species due to overharvesting but, it wasn’t until about 40 years later that peyote was identified as a vulnerable species by the International Union for the Conservation of Nature (IUCN) (Ermakova et al., 2021).  Currently, peyote is being used more than ever before; the growing demand for peyote worldwide is increasing the amount harvested from the wild, further threatening the species (Kleffens et al., 2023). Since the wild population of peyote has been substantially reduced in terms of distribution, density and even size, this necessitates the implementation of micropropagation and controlled cultivation facilities, if the demand for peyote is to be met without further threatening the vulnerable species (Kleffens et al., 2023; Serrano & Quintana, 2007).   

Micropropagation of peyote was successfully achieved in the 1990’s and while it is currently utilized to produce plants for scientific study, it has yet to be implemented in the production of peyote for ceremonial uses (Kleffens et al., 2023; Serrano & Quintana, 2007).  Micro-propagation of peyote is accomplished by applying cytokinins to the tissue-culture media of shoot tissue explants; this reduces the auxin-mediated apical dominance, allowing for activation of the dormant areolar meristems (Serrano & Quintana, 2007. The primary reason for the lack of development in the cultivation of peyote is the legal status of the plant and its alkaloid, mescaline (Kleffens et al., 2023).   

In the United States, peyote is classified as a Schedule I drug and while an exemption exists for the Native American Church, this only allows for members of the church to harvest, possess and use the plant for religious ceremonies, not grow it. It’s worth noting that the current drug scheduling in the United States identifies peyote as having no medicinal uses and a high potential for abuse and addiction, despite a scientific consensus that it has a very low potential for abuse (Drug Enforcement Administration, 2022; Bouayad, 2019; Kleffens et al., 2023). For use in research, a permit must be obtained from the Drug Enforcement Administration, the researchers must also abide by strict guidelines, creating a major hurdle (DEA, 2022; Kleffens et al., 2023). In Canada a similar issue exists for researchers studying mescaline specifically, since when extracted it is recognized as a Schedule III substance but, peyote itself is not classified as a drug, so the possession and cultivation of the plant is allowed (Health Canada, 2023).   

III. Medicinal Uses  

Upon European arrival to North America, some medicinal properties of peyote were widely known and as such it was documented to have been used by Native Americans for the treatment of fever, snake bites, stings, burns and other wounds (Kleffens et al., 2023). Currently, peyote and its extracts are being studied worldwide for their use in cancer therapy, as an antibacterial agent and even as a potential treatment for lupus (Ahmad et al., 2022; Kleffens et al., 2023; Orozco-Barocio, 2024). One field of research that continues to generate positive results is the use of mescaline for treating various psychological conditions. Among members of the Native American Church (NAC), it has been widely reported that peyote meetings have played a crucial role in helping many members recover from their struggles with alcoholism. A 2021 study showed that naturalistic mescaline use had a positive effect on 68% – 86% of study participants afflicted with post-traumatic stress disorder, depression, anxiety or drug use disorders, demonstrating a widely held belief of the NAC (Kleffens et al., 2023).   

IV. Spiritual & Ceremonial Uses  

It was documented that in the early 16th century, at the time of European arrival in North America, the ceremonial use of peyote was widespread in the Aztec Empire and among various indigenous groups (Kleffens et al., 2023). However, there is archaeological evidence that indicates peyote was used by indigenous people(s) as far back as ~3,700 BCE, about 5,200 years before the first record use (El-Seedi et al., 2005).   

The peyote ceremony was first documented in the late 19th century and was described as a nightlong ritual used to modify an individual’s consciousness and induce a state of introspection, allowing them to receive profound insights and undergo therapeutic self-transformation (Calabrese, 2013). The ceremony is typically held in a tipi and led by four main officiants, the Road Man, Drummer Man, Fire Man and Cedar Man, each of whom play a specific role to ensure the ceremony is successful. The peyote ceremony is traditionally held for one of two reasons, doctoring meetings are held to heal a specific person or ailment while appreciation meetings are held to express thanks or to celebrate a new phase of life, like when a child is born, a marriage occurs or even after a person dies (Calabrese, 2013).

Sage: Salvia apiana  

I. Botany  

Salvia apiana is a popular species of the salvia genus, which is the largest genus of the lamiaceae family (Afonsa et al., 2019). It is both a sacred and medicinal plant in many North American Indigenous cultures. The S. apiana species specifically is used primarly by the Chumash people in southern California (Krol et al., 2021). It is a part of the chaparral shrub community, common in California and northern Baja California as an endemic species (Krol et al., 2021). The plant is an herb or subshrub that grows to be one to three metres tall (Krol et al., 2021).  

It is a perennial that forms rounded shrubs, with a woody base and tomentose layer on the branches (Krol et al., 2021). The root system may penetrate up to 1.5 metres deep, and is branched and fibrous (Krol et al., 2021). The leaves are wide but lanceolate, 4-8 centimetres long, and pale green with crenulate margins (Krol et al., 2021). They also have a silver sheen on them from oil glands and dense hairs (Krol et al., 2021). The flowers are white to pale purple, and covered in appressed trichomes, with a corolla that is made of two lips, with a smaller top lip, and a larger bottom lip that obstructs the corolla chamber entrance (Krol et al., 2021). Each flower is surrounded by 5.0-7.5mm long calyxes and has two 14-17mm long stamens, which each have two pollen stacks (Krol et al., 2021). The flower shape adapted to accommodate large pollinators such as carpenter bees, honeybees, and bumblebees (Krol et al., 2021). The fruit of S.apiana is a 3-5mm light brown nutlet (Krol et al., 2021).

Figure 2Hand drawn by Amiro, P., 2025. Diagram of a full branch of Salvia apiana and a labeled leaf. S. apiana leaves are pale green, 4-8cm in length, have crenulate margins, a tomentose layer, and are wide and lanceolate.

Variations in the morphology of S. apiana may vary based on location (Krol et al., 2021). The compacta variety found on the edge of deserts are more likely to have open and more densely branched panicles (Krol et al., 2021). However, the typica variety found on coastal slopes is more likely to have compact panicles (Krol et al., 2021). It is a drought resistant plant, and habitats areas with low annual rainfall and high summer temperatures (Krol et al., 2021). Its coastal habitat is historically susceptible to wildfires, which the plant has adapted to accommodate, by having basal burls to allow recovery after fires (Krol et al., 2021).  

In recent years, commercialization of S. apiana has increased and there has been a decline in population (Krol et al., 2021). While the plant is not currently threatened, its narrow distribution increases its risk for rapid decline (Krol et al., 2021). Its risk is predominately due to recent reports of large amounts of illegal sage harvesting in protected areas (Krol et al., 2021). White sage may become endangered due to poachers who extract large amounts to sell for commercial smudge stick sale (Rudnicki, 2020). They often clear-cut sage plants at the base, which does not allow for continued growth (Rudnicki, 2020). The increased harvesting may be attributed to the recent popularization of smudging as a casual social phenomenon among nonnative people in North America (Rudnicki, 2020).

II. Propagation & Cultivation  

Cultivation of S. apiana in greenhouses and for personal use includes difficulties getting roots from cuttings, low success with growth from seed, and slow and erratic germination (Rudnicki, 2020). After rooting, plants are also slow to grow to large sizes and may take years to do so (Rudnicki, 2020). They are not well adapted to most of North America and are specific to areas of low elevation in California (Rudnicki, 2020). When planted in their native region, they are sowed best in soil when planted in cool autumn, before the wet winter, which allows for optimal growth (Rudnicki, 2020). Outside of their native range, they are best sowed when planted in the spring, once the weather warms (Rudnicki, 2020). S. apiana does best in a soilless mixture with organic matter and should not be planted with regular gardening soil (Rudnicki, 2020). Their wide spreading root system means care should be taken when digging near where they are planted (Rudnicki, 2020). They thrive best in warmer climates, and while some estimates say they can tolerate climates where temperatures reach minimums of 0 degrees Fahrenheit, it is recommended that they are planted where temperatures reach a minimum of only 10 degrees Fahrenheit (Rudnicki, 2020). S. apiana does not thrive well in overly wet soil, and prefers aerated, mineral-rich soil with good drainage, which may be provided by a slope, such as in their native environments (Rudnicki, 2020). They require a minimum of six hours of full sun to thrive, as well as significant air circulation (Rudnicki, 2020). After planting, regular watering will help roots establish, but they ideally survive on light rainfall alone and can fail easily with a few days of heavy rainfall or overwatering (Rudnicki, 2020).   

The cultivation supply chain for S. apiana is currently an unregulated market, and projects that protect this Indigenous cultural resource are being proposed (Fessler, 2021). The overcultivation and popularized casual use of sage is akin to cultural appropriation and can negatively affect Native American’s ability to harvest and use this plant that is vital for cultural practices (Fessler, 2021) (Rudnicki, 2020). According to Chumash tradition, S. apiana should be collected with prayer, like all plants, and only the amount needed should be collected, but some may be dried for later if necessary (Adams & Garcia, 2005). One study showed the ability to establish micro shoot cultures, which produce a significant amount of biologically active essential oil from S. apiana (Krol et al., 2023). This demonstrates the ability to maintain a source of S. apiana volatiles without overexploitation of the plant from its natural habitat (Krol et al., 2023).  

III. Medicinal Uses  

The medicinal uses of S. apiana are vast and have been well known my Indigenous tribes, which have used white sage medicinally for around 13,000 years (Adams & Garcia, 2005). It is an edible species, highly aromatic, and rich in essential oils and phytochemicals including phenolic acids, terpenes, and flavonoids. (Afonsa et al., 2019). Examples of prominent phytochemicals include rosmarinic acid, β-pinene, and salvigenin. S. apiana decoction has shown incredible antioxidant activity, particularly in lipid peroxidation events (Afonsa et al., 2019). S. apiana essential oils have also demonstrated the ability to inhibit acetylcholine-esterase (AChE), providing evidence it may be beneficial in neurodegenerative diseases (Krol et al., 2023). It has also shown a remarkable ability to combat nitrous oxide, a pro-inflammatory marker, and be one third as effective as dexamethasone, an anti-inflammatory pharmaceutical (Afonsa et al., 2019). S. apiana is tumor selective as well, and has demonstrated cytotoxic effects against tumor cells, particularly against hepatocellular carcinomas, cervical carcinomas, and breast cancer carcinomas, all while having little cytotoxic activity on normal cells (Afonsa et al., 2019). Antibacterial and bactericidal activity against several gram-positive and gram-negative bacteria has been demonstrated by the plant as well (Afonsa et al., 2019). Medicinal practices in Native American culture using S. apiana include not only administration of the compound, but also prayers and sacral actions by specified healers (Krol et al., 2021).  

IV. Cultural & Ceremonial Uses  

Historically, S. apiana has been used most by the tribes in Southern California and surrounding areas, as that is where the plant is native to. These tribes include the Cahuilla, Chumash, Kumeyaay, Luiseno, and Tongva (Rudnicki, 2020). The plant has been used by these tribes for basket making, food, healing, and purification (Rudnicki, 2020). To promote the next season’s growth, the Chumash and Chahilla had a custom to burn grassland or chaparral areas with sage shrubs (Krol et al., 2021). S. apiana is often used by healers to initiate healing, to help a person maintain integrity and purify the central nervous system; setting the spirit back to normal (Adams & Garcia, 2005). It is often the foundation of treatment, helping a patient be calm and rational (Adams & Garcia, 2005). The best use is in a patient’s water; the suggested method is to place an entire leaf into 1L of water and wait half an hour for it to infuse before the patient drinks (Adams & Garcia, 2005). They may also put half a leaf in the mouth and suck on it to soothe the throat, or make tea by bringing the water to almost a boil with the sage leaf in it (Adams & Garcia, 2005).  

For smudging use, small (about 6 inch long) dried branches are used (Adams & Garcia, 2005). It is spirit medicine, used for blessings, and should not be burned like incense (Adams & Garcia, 2005). Everyone should be praying when smudging is occurring, because smoke from smudging with white sage brings the prayers to God and invites him to participate in healing (Adams & Garcia, 2005). Only certain people are invited to administer blessing with white sage, in addition to healers that may use smudging for the healing process (Adams & Garcia, 2005).   Historically, harsh Church practices in colonial times resulted in forced conversion of Southern Californian Indigenous people to Roman Catholicism (Rudnicki, 2020). As a result, some are still Roman Catholic, and merged traditions have resulted in smudging being incorporated into services where many Native American people attend (Rudnicki, 2020).   

Tobacco: Nicotiana   

I. Botany  

The genus Nicotiana is found within the Solanaceae or ‘nightshade’ family and is recognized as the tobacco plant (Coggins & Richter, 2014). The two most common forms are Nicotiana tabacum, for commercial use and Nicotiana rustica, representing the wildtype, with approximately 75 known species in total (Coggins & Richter, 2014). N. tabacum and N. rustica have a higher nicotine content and larger leaves than earlier wild varieties due to genetic selection and modification by the early peoples of South America (Tushingham et al., 2018). Indigenous communities of North and South America have been using other species of tobacco for centuries mainly for spiritual and ritual purposes, with N. tabacum becoming popular in these regions by the 1500’s over N. rustica and other wildtypes because of its “smoothness” (Tushingham et al., 2018). The 1600’s saw tobacco farming skyrocket with the introduction of tobacco as a global trade commodity and “mass consumable” (Tushingham et al., 2018). Large scale production not unlike modern times, began around the early 1880’s (Coggins & Richter, 2014).  

Commercialized tobacco, or N. tabacum, is farmed in anthropogenic areas for the sole purpose of harvest for the cigarette and cigar industry. The leaves of this dicot are the target harvest segment of the plant. It is a flowering plant with five petals and stamen and a dry, splitting fruit as small as 1-2mm in length and has broad leaves with smooth blades (Native Plant Trust, n.d.). The leaves and roots are susceptible to disease and pests, mosaic and nematodes respectively (Allaby et al., 1998, p. 449) (Tungamirai Makunde, Zeng, & Patel, 2023). Tobacco Mosaic Virus, or TMV, is a single-stranded RNA virus which is stable and mechanically spread, a persistent disease for which there is no current cure (Penn State Extension, 2023).  

Tobacco was and still is popular today for consumption purposes (in addition to ritual use) due to its biochemical makeup. The active and predominate metabolite in tobacco is the alkaloid nicotine – a highly addictive and powerful insecticide (Allaby et al., 1998, p. 300). As is characteristic with the solanaceae family, tobacco contains a large variety of alkaloids (Coggins & Richter, 2014). These alkaloids have agnostic effects on the variable nicotinic receptors abundant within the human body, resulting in diverse effects such as stimulation or tranquility depending on length and dose ingested (San Andrés Larrea et al., 2014). Other metabolites in tobacco include phytochemicals, polysaccharides, ammonia, formaldehyde etc. (Zhang et al., 2024). Although the plant requires intensive interventions to process, tobacco plants have a short growing season, are prolific seeders, have strong genetic diversity, and are aneuploidy – all factors ideal for research and experiments (Coggins & Richter, 2014).   

II. Propagation & Cultivation  

Tobacco plants are farmed on a mass industrial scale to supply the demand of cigarette and cigar consumers. Conversely, it is also managed on small scales by Indigenous peoples of the Americas, with spiritual intent and little inputs and technology involved. Commercial cultivation of N. tabacum spans an approximate 100-130 days from transplant to maturity (McMurtrey, 2025). Most tobacco is planted by hand, and requires well-draining soils, with fertilizer requirements varying with climate and soil makeup (McMurtrey, 2025). Terminal growth is pruned to encourage the plant to grow laterally, broadening the leaves, and the flower is later removed for the same reason – limiting apical growth (McMurtrey, 2025). The most common commercial harvest practice is whole-plant harvesting, cutting away the entire tobacco plant and later drying the leaves (McMurtrey, 2025). On smaller-scale production or with traditional tobacco wildtypes, the leaves are picked off individually through priming at intervals which keep the plant alive and intact (McMurtrey, 2025). Curing processes such as by air, fire, flue or sun can alter the final product – the most common technique being air curing (Coggins & Richter, 2014) (McMurtrey, 2025). Finally, the dried leaves (slightly moistened for handling purposes) are then graded, confirming quality of the leaf and deeming it ready for sale (McMurtrey, 2025). Propagation of tobacco plants is done in controlled seedbeds, which is fairly easy and non-risky because of tobacco plant’s abundant seed production (Coggins & Richter, 2014). Vegetative propagation is not typically necessary or practiced (Coggins & Richter, 2014).  

III. Medical Significance  

Due to the ease of genetic manipulation of tobacco, it has been used in countless studies to aid in drug development and disease relief (Powledge, 2004) (Tremblay et al., 2009). Studies have been done to support the use of tobacco derived nicotine in patients with Parkinson’s disease to protect dopaminergic neurons, and in patients with Alzheimer’s to improve attention and memory by stimulating nicotinic acetylcholine receptors (Powledge, 2004). Tobacco was the first plant antibody approved for human use in 2005 and was first used for functional full length recombinant antibodies (Tremblay et al., 2009). Its effectiveness in molecular farming of pharmaceuticals can be attributed to its high leaf biomass and high soluble protein content (Tremblay et al., 2009). The species Nicotiana benthamiana has been used to create a flu vaccine used in trials on over 22,000 participants, resulting in 35% more effectiveness in adults than the normal flu vaccine that year (Jarvis & Campanella, 2021) (Tregoning, 2020). The ingestion of tobacco products is known to lead to health complications, such as the FDA’s identified top 5; cancer, cardiovascular disease, respiratory effects, developmental or reproductive effects, and addiction (Coggins & Richter, 2014). However, tobacco waste (non-leaf biomass) has potential benefits and is worth further study for extracted health products and bioactive components (Zou et al., 2021).  

IV. Spiritual & Ceremonial Uses  

Wild varieties of tobacco have been used in Native cultures long before its introduction as a recreational drug in the form of cigarettes and cigars. Tobacco is one of four plants sacred to North American Indigenous communities, the others being sage, cedar, and sweetgrass which are all integral to Medicine Wheel teachings of interconnectedness (Tribal Trade, 2020). Tobacco smoke is believed to be the connection to the spirit realm, allowing living people to communicate with their ancestors and the Creator (National Collaborating Centre for Aboriginal Health, 2013). Most ceremonial practices involving tobacco are in the form of smudging – where dried leaves are burned either in isolation or over a fire for cleansing, prayer, and thanks (National Collaborating Centre for Aboriginal Health, 2013). Other non-ingested spiritual uses include placing on water or placing on the ground as an offering after a hunt, to honour the animal and protect its spirit as it travels from the Earth (National Collaborating Centre for Aboriginal Health, 2013). The cultivation of tobacco plants is a spiritual practice in and of itself for Indigenous communities (First Nations Health Authority, 2022). It begins with traditional burning practices used to prepare the soil and turn over nutrients (First Nations Health Authority, 2022). The planting, harvesting, and curing are then all completed in a positive mindset and with intent and respect for the Creator and Earth’s gifts (First Nations Health Authority, 2022). This small-scale farming of tobacco usually involves species like N. rustica and other wildtypes and takes advantage of the individual leaf harvesting method. Due colonization, bans on ceremonial tobacco cultivation, sale, and usage were once enacted, leading to the encroaching of N. tabacum into Indigenous communities, increasing frequency of ingestion of the plant and therefore driving up dependency and addiction rates for these communities (Nez et al., 2022).

V. Wellness Applications  

Overall, tobacco research has led to discoveries in plant biotechnology like photoperiodism, medical understandings and advancing public health information (Tso, 2006). Current studies are looking into tobacco plants for supporting environmental wellness through phytoremediation. This is the process of tobacco plants absorbing toxins, heavy metals, and pollutants from soil through their roots (Bhat et al., 2022) (Gisbert et al., 2020). As a hyperaccumulator plant species, tobacco (specifically shrub varieties) is being genetically edited to increase synthesis of heavy metal binding ligands to improve their success with phytoremediation (Bhat et al., 2022). Implementing tobacco plants in industrial areas could be an eco-friendly clean-up solution while simultaneously introducing greenery and carbon stores into urban spaces.   

Conclusion   

Peyote, white sage and tobacco demonstrate the connection between people and medicinal plants. Throughout this paper, the plants’ botany, methods of growing, medicinal uses, ceremonial roles, and modern uses in health advancements were discussed. This further demonstrates how traditional indigenous knowledge has been a pathway in species use for many generations. In recent years, modern science has continued to study the healing properties and chemical compounds of plants, and their cultural and spiritual significance remains as important as the medicinal uses.   

The Peyote species clearly examines how plants are closely tied to their effects and ceremonial uses. The species’ significant use for healing and spiritual purposes is at risk of potential threats. These threats are posed by over-harvesting and the laws which are in place, making it difficult to grow and study the plant. White sage is known for the healing and cleansing factors within the plant and is also at risk due to illegal harvesting for commercial demand and cultural exploitation. Tobacco, although it is commonly used in recent years in healthy commercial products, as a connection to spiritual significance. Tobacco is used in many indigenous communities as a sacred offering and also as a way to connect to the spiritual world. Tobacco has an important role in modern science as it could potentially develop vaccines, medicine and can be used to remove pollutants from the environment, such as heavy metals and toxins. 

Ongoing issues for these species are sustainability and respect for cultural significance. The rising commercial demand, environmental damage and the global consumer market have placed a huge burden on these sacred plants. Protecting these plants by conservation methods, propagation and indigenous knowledge is important to ensure that the plants are available for traditional uses and future scientific studies. Overlooking the indigenous harvesting practices, spiritual traditions, which were passed down and the environment. Could essentially cause these plants to be at a greater risk.  

These plants also play a crucial role in the overall health and well-being. Peyote, white sage and tobacco help in the guidance of mental and spiritual health through practices such as ceremonies, rituals and healing. This method of healing focuses on the overall well-being of an individual rather than only focusing on treating physical symptoms; it differs from many modern medical approaches.  

Overall, peyote, white sage and tobacco demonstrate the various connections between botany, traditional medicine, spirituality and recent plant research. Their ongoing use in both scientific research and indigenous practices demonstrates how important they are in both nature and culture. These plants continue to gain attention and interest. It is important that future research, cultivation and commercialization are done in a way to respects the culture, environment, and indigenous knowledge. By ensuring the plants are respected in every aspect, it would allow them to be protected and used as a source of healing and knowledge for future generations.
