Solomon’s Seal (Polygonatum multiflorum)

Arnica is an aromatic perennial, usually about 1 ft (30 cm) high, with downy, oval-shaped leaves and bright yellow daisy-like flowers. Its flowers and roots have traditionally been used for bruises, sprains, arthritic pain and muscle aches, and a highly diluted form is used in homeopathy; MSK says a few clinical trials suggest topical arnica may help osteoarthritis and bruising, but rigorous research on homeopathic arnica is still needed. Arnica taken internally can be toxic (see precautions).

Corydalis is a small herbaceous perennial growing to 8 inches with narrow leaves and pink flowers. Native to Siberia, northern China, and Japan, it is commonly cultivated in eastern and northeastern parts of China. Propagated from seed in early spring or autumn, the rhizome is harvested in late spring and early summer when the aerial parts have withered. It has been part of Chinese herbal medicine since at least the 8th century.

Lobelia is an annual herb growing to 20 inches with lance-shaped leaves and pale blue, pink-tinged flowers. It was used as a 'puke weed' to induce vomiting. Lobelia was also smoked as a substitute for tobacco and was reputed to share some of its magical qualities. Indigenous to North America, especially eastern parts of the United States, it grows by roadsides and in neglected areas, preferring acid soil. The aerial parts are harvested in early autumn when the seed capsules are most numerous and are carefully dried. Its use was later championed by the American herbalist Samuel Thomson (1769-1843), who made the herb the mainstay of his therapeutic system, mainly using it to induce vomiting.

Myrrh is a resin obtained from several Commiphora species, notably C. myrrha, recognized by its thick, yellowish-red gum resin. It is bitter in taste and aromatic.

Siberian ginseng (Eleutherococcus senticosus), also called Eleuthero, is a deciduous, hardy shrub reaching up to about 10 ft (3 m). It features 3-7 toothed leaflets per stem and spiny branches. Regarded as an adaptogen, Siberian ginseng has been used traditionally as an adaptogen, performance enhancer and immunostimulant; MSK says studies in humans are quite limited.

Turmeric (Curcuma longa) is a perennial with a thick rhizome, growing to about 3 ft (90 cm), featuring lance-shaped leaves and pale yellow flowers. Renowned for its bright yellow-orange color, turmeric is a spice commonly employed in Indian cooking and in Ayurveda, where it has been used for indigestion, colds, skin infections, and arthritis. NCCIH says there isn't enough evidence to conclude that turmeric or curcumin is beneficial for any health purpose.

Wintergreen (Gaultheria procumbens) is a low-lying evergreen shrub, reaching about 6 in (15 cm), with oval leathery leaves, small bell-shaped flowers, and bright red berries. It is known primarily for its oil, which contains methyl salicylate.
