Additional recommended knowledge
Use and availability
European and Asian plants are commonly used in herbalism and are generally available in retail shops.
Medicinal plants of the American West are generally not as available, but can be grown in gardens. Collecting plants in nature may be illegal without a proper permit.
Native Americans of the West routinely use these plants in health care.
Among Native Americans spiritual health and physical health are inseparable.
In fact, an unhealthy spirit leads to an unhealthy body. Most Native American healers start by healing the spirit, then the body. Prayer, singing, talking and comforting are an essential part of healing.
Many traditionally used plants are ritualistic or shamanistic in nature, prompting interest as recreational or hallucinogenic uses of western plants, such as peyote, Lophophora williamsii, California Jimson weed and others.
Jimson weed, Datura wrightii and Datura stramonium, as well as most other Datura species, can cause respiratory depression and death when not used in carefully controlled dosage.
These plants have been used for centuries by Native Americans to induce sacred dreams, as a spiritual experience. Some of these plants were also used in rites of passage.
The following plants are routinely used by American Indians, and have come to be recognized as safe by virtue of historical and continued use without deleterious effects to health.
- Black sage, (Salvia mellifera), can be used against pain. A strong sun tea of the leaves and stems of the plant can be rubbed on the painful area or used to soak one's feet. The plant contains diterpenoids, such as aethiopinone and ursolic acid, that are pain relievers.
- California bay (Umbellularia californica) leaves are used to treat pain.
- California poppy (Eschscholzia californica) can be chewed to treat toothache, and to decrease milk production in nursing mothers anti-galactogogue.
- California sagebrush, (Artemisia californica), can bring back pleasant memories. The smell of the leaves and stems is pleasant and relaxing. The plant has many fragrant monoterpenoids that are soothing to smell.
- Douglas' sagewort, (Artemisia douglasiana), is used to induce dreaming, as well as an antibacterial and douche. Leaves and stems under a pillow at night can help sleep as well as induce dreams. Anti-microbial action comes from: camphor (29%), artemisia ketone (26%), artemisia alcohol (13%), α-thujone (10%), 1,8-cineole (8%), and hexanal (5%). The plant contains many fragrant monoterpenoids that may help with dreaming.
- Horsetail or Scouring Rush (Equisetum spp.) is used as a diuretic because of it contains high concentrations of oxalic acid and calcium oxalate and therefore can also be a throat irritant if brewed improperly.
- Matilija poppy, (Romneya coulteri) is applied topically to treat sunburn.
- White sage, (Salvia apiana) can be grown in a garden and used every day to purify the spirit. One leaf is placed in a water bottle, and used normally. Sucking on a leaf can soothe sore throats since the leaves contain camphor and other therapeutic compounds:
- Yarrow (Achillea millefolium) is used for various ailments including cramps, fevers, and toothache.
- Yerba Buena (Satureja douglasii & Clinopodium douglasii (by region) is used as a refreshing tisane to treat dehydration.
- Yerba Mansa (Amenopsis Californica) is used as an antimicrobial, to treat venereal disease in part due to concentrations of: 4-allylveratrole, esdragol, thymolmethylether, linalool, and para-cymene, 1,8-cineol, d-limonene, camphene, alpha pinene and beta-pinene.
- Yerba Santa, (Eriodictyon californicum) and other Eriodictyon species, was used in American and British hospitals and clinics for respiratory infections, influenza, tuberculosis and asthma until 1960. In that year, a law was passed requiring that all medicines had to have proven efficacy. Yerba santa is used by crushing 3 leaves in a cup of hot water and slowly drinking the tea.
