Devil's Claw (Harpagophytum procumbens)

Gravel root is an erect perennial growing to 5 feet with whorls of pointed oblong leaves and clusters of purple-pink florets. Native to eastern North America, the root is unearthed in autumn. The plant's alternative name, Joe Pye weed, honors the Native American said to have used it to cure New Englanders of typhus. Native Americans valued the herb as a diuretic and remedy for genitourinary conditions, and the root was listed in the Pharmacopoeia of the United States from 1820 to 1842, attesting to its recognized medicinal importance.

Pipsissewa (Chimaphila umbellata) is an evergreen plant about 8 in (20 cm) tall, with glossy, wedge-shaped leaves and small, pinkish-white flowers in flat-topped clusters. A close relative of uva ursi, pipsissewa shares urinary antiseptic properties and is notably gentler on the kidneys.

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. Known primarily for its oil containing methyl salicylate - a natural anti-inflammatory and analgesic compound - it has long been used for topical pain relief.

Black cohosh (Cimicifuga racemosa) is a tall herbaceous perennial, growing up to about 8 ft (2.5 m) with creamy-white flower spikes. Its thick, knobby root has a bitter, acrid taste and a distinctive odor. Traditionally, the root has been valued as a Native American remedy for women’s health issues, especially painful periods, menopausal problems (such as hot flashes), and uterine discomfort. It also has a history of use for rheumatic complaints, including rheumatoid arthritis, nerve conditions like tinnitus, and even venomous bites or stings. Modern research suggests black cohosh can help alleviate menopausal symptoms and may influence estrogenic activity within the body, although it does not contain estrogen itself.

Blue cohosh is an upright perennial herb reaching 3 feet in height, with large three-lobed leaves, yellow to purple flowers, and striking blue berries. It grows wild in much of eastern North America from Manitoba to Alabama, preferring woodland valleys and damp, north-facing slopes. The name 'cohosh' comes from the Algonquin language, and the plant was a popular remedy among many Native American tribes. Though taken by both sexes for genitourinary issues, it was primarily valued as a women's herb, and that tradition continues in modern herbal practice.

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. This important Chinese remedy has been used at least since the 8th century to help 'invigorate the blood' and relieve almost any painful condition, particularly menstrual cramps and chest and abdominal pain.

Biennial herb growing to 8 in (20 cm). Has red blotches on stem, crinkled lance-shaped leaves, 4-petaled yellow flowers, and elongated seed capsules. The flowers, leaves, and stem bark of evening primrose have astringent and sedative properties. All three parts have been employed in the treatment of whooping cough. Evening primrose has also been taken for digestive problems and asthma, and used as a poultice to ease the discomfort of rheumatic disorders.

Juniper (Juniperus communis) is a coniferous shrub or small tree that may reach about 49 ft (15 m). It bears needle-like leaves, male and female flowers, and spherical blue-black “berries” (actually seed cones) rich in potent volatile oils. Juniper berries have been used for centuries as a flavoring (notably in gin) and for their antiseptic, diuretic properties.
