Caraway (Carum carvi)

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. Its name comes from the Norse word 'dylla,' meaning 'to soothe,' reflecting its calming properties. Catnip has an excitatory effect on cats but a sedative effect on humans.

Dill is an aromatic annual growing to 30 inches with an erect hollow stem, feathery leaves, and numerous yellow flowers in umbels. Its very lightweight, pungent fruit (seeds) are harvested in late summer. Native to southern Europe and central and southern Asia, dill grows wild in open areas and is widely cultivated - notably in England, Germany, and North America. The leaves are picked as a culinary herb. An ancient Egyptian remedy in the Ebers papyrus (c. 1500 BCE) recommends dill as one of the ingredients in a pain-killing mixture. The ancient Greeks are believed to have covered their eyes with fronds of the herb to induce sleep. Dill was commonly used as a charm against witchcraft in the Middle Ages, when it was burned to clear thunderclouds. Its name comes from the Norse 'dylla,' meaning 'to soothe.'

Oregano (Origanum vulgare) is an upright perennial up to around 32 in (80 cm), bearing square red stems, elliptical leaves, and clusters of deep pink flowers. Strongly antiseptic and aromatic, oregano is useful for respiratory, digestive, and fungal infections, as well as being a culinary herb.

Peppermint (Mentha × piperita) is a fast-growing, square-stemmed herb (commonly about 32 in / 80 cm tall), with lanceolate, serrated leaves and purplish flowers. A natural hybrid of watermint and spearmint, peppermint is renowned for its cooling, aromatic flavor and its therapeutic benefits in alleviating digestive and respiratory complaints.

Common plantain (Plantago major) is a low-growing perennial reaching up to about 10 in (25 cm), forming a rosette of broad, ribbed leaves and spikes of tiny green flowers. Often regarded as a garden weed, plantain’s leaves are rich in iridoids, flavonoids, mucilage, and tannins, making them potent for wound care and internal soothing of mucous membranes.

Chinese rhubarb (Rheum palmatum) is a thick-rhizomed perennial, growing up to 10 ft (3 m) tall, with large, palmate leaves and small flowers. Known in Chinese medicine for over 2,000 years, it has a paradoxical effect on the bowels: stimulating in large doses, yet gently astringent and constipating in small doses. The rhizome also aids digestion, helps counter inflammation, and has anti-ulcer and antibacterial actions.

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 has balanced energy with five flavors (bitter, sour, astringent, salty, and sweet), acting as a mild laxative that tones intestinal membranes, lubricates tissues, and relaxes muscle spasms. Bibhitaki is pungent, warming, antispasmodic, and serves as an expectorant and decongestant for respiratory conditions. Amalaki also has balanced energy with five flavors (sour, astringent, sweet, pungent, and bitter), containing small amounts of anthraquinones while being astringent, thus both laxative and bowel-toning, correcting both constipation and diarrhea.

Horehound (Marrubium vulgare) is a square-stemmed perennial of about 20 in (50 cm) height, featuring fuzzy, downy greenish-gray leaves and small, white, double-lipped flowers. Known for its aromatic bitterness, horehound has a longstanding history in cough syrups and lozenges.
