Black Pepper (Piper nigrum)

Triphala is not a single herb but a traditional Ayurvedic blend of three fruits: haritaki (Terminalia chebula), bibhitaki (Terminalia bellirica), and amalaki or Indian gooseberry (Emblica officinalis). Haritaki is described in Ayurveda as having five flavors (bitter, sour, astringent, salty, and sweet). Bibhitaki is described as pungent and warming. Amalaki is also described as having five flavors (sour, astringent, sweet, pungent, and bitter) and contains small amounts of anthraquinones.

Bacopa, also known as Water Hyssop or Brahmi, is a creeping succulent perennial that can grow to about 20 inches. It features spatula-shaped fleshy leaves and pale blue or white flowers on slender stalks. It thrives in marshlands and along the edges of mangrove swamps in warmer temperate and tropical climates, especially southern Asia, where it forms dense mats on mudflats.

Bay laurel (Laurus nobilis) is an aromatic evergreen shrub or small tree that can grow up to about 65 ft (20 m). It features leathery, dark green, lance-shaped leaves, small yellow flowers, and shiny black berries. The plant is well known for its culinary use (“bay leaves”) as well as its medicinal history in ancient Greece and Rome.

Boldo is a strongly aromatic multi-branched evergreen shrub or tree growing to 20 feet. It has egg-shaped leathery leaves with a lemony scent, clusters of white or yellow bell-shaped flowers, and small yellow berries. Native to Chile and Peru, it has become naturalized in the Mediterranean region and the West Coast of North America, where it grows on dry sunny slopes and in mountain pastures in the Andes. It is widely cultivated, and its leaves are gathered throughout the year.

Catnip is a downy, aromatic perennial growing to 3 feet with heart-shaped, gray-green leaves and whorls of white flowers marked with purple spots. Native to Europe and naturalized in North America, it grows in dry wayside places and mountainous regions up to altitudes of 5,000 feet. The plant is gathered when in flower during summer and autumn. Catnip has an excitatory effect on cats.

Cat's claw is a climbing vine that can grow to 100 feet or more, with stems up to 8 inches in diameter, large glossy leaves, and sharp hooks resembling a cat's claws. Native to tropical rainforests in the central and eastern Andes, especially Peru, Ecuador, and Colombia, it has also been found in Guatemala, Costa Rica, and Panama. Indigenous people of the Amazon rainforest have used cat's claw for centuries to ward off disease, and NCCIH says it is promoted today for osteoarthritis, rheumatoid arthritis, cancer and viral infections. NCCIH says there is no conclusive evidence from studies in people to support cat's claw for any health purpose. By the early 1990s, over-collection from the wild threatened the species' survival; only sustainably sourced stem bark should be used, rather than root bark.

Clove (Syzygium aromaticum) consists of the dried, unopened flower buds of an evergreen, pyramid-shaped tree that can reach about 49 ft (15 m) in height. Known for their potent aroma and taste, cloves have a significant history both as a culinary spice and as an herbal medicine, particularly in India and Southeast Asia. Clove’s volatile oil is rich in eugenol. Clove oil is an irritant and must be used with caution on the skin.

Codonopsis is a small twining perennial growing to 5 feet with oval leaves and pendulous green and purple bell-shaped flowers marked with purple in summer. Native to northeastern China and growing throughout the region, especially in the Shanxi and Szechuan provinces, it is propagated from seed in spring or autumn, and the root is harvested in autumn once the aerial parts have died down. Codonopsis holds a central place in Chinese herbal medicine.
