Catnip (Nepeta cataria)

Linden comprises deciduous trees growing to a height of 100 feet with smooth gray bark, heart-shaped leaves, and clusters of pale yellow flowers with winglike bracts. Native to Europe, it is found in the wild but is also much planted in gardens and along roads. The flowers are collected in summer. Greek myth recounts how the nymph Philyra, devastated after being raped by the god Cronus in the guise of a horse and giving birth to the centaur Chiron, begged the gods not to leave her amongst mortals. The gods granted her wish by transforming her into a linden tree, forever linking this graceful species with transformation and divine mercy.

Andrographis, commonly known as Green Chiretta or King of Bitters, is an upright annual herb reaching approximately 3 feet in height. Native to India and cultivated throughout northern regions of India and China, this bitter medicinal plant has been valued in Ayurvedic and traditional Chinese medicine for centuries. MSK notes that it has been studied mostly for colds, flu and upper respiratory infections. The plant thrives on plains and in forest undergrowth, where its spotted pale brown or purple flowers and long seed capsules distinguish it from other medicinal herbs.

Black pepper is a perennial woody climbing vine growing to about 16 feet, with large oval leaves, spikes of small white flowers, and clusters of small round fruits that ripen from green to red. Native to southwestern India and now cultivated in tropical areas worldwide, the fruit is harvested from plants that are at least three years old. Different processing methods yield green, black, red, and white peppercorns, each with distinct flavors and uses. Cultivated as both a spice and medicine since ancient times, pepper was such a prized commodity in world trade that Attila the Hun reportedly demanded 3,000 pounds of it as ransom during his siege of Rome in 408 CE.

California poppy (Eschscholzia californica) is an annual or short-lived perennial with finely divided leaves and vibrant orange, yellow, pink, or red blossoms. It is related to the opium poppy.

Caraway is an aromatic annual herb growing to 2 feet with a ridged stem, feathery leaves, and umbels of white flowers in midsummer. Exploding capsules release two small narrow seeds. It grows wild in Europe, North Africa, and Asia, preferring sunny sites up to 6,600 feet above sea level. Cultivated in Europe, Russia, North Africa, and the United States, the seeds are harvested ripe in late summer. The seeds are commonly used in cooking.

Cinnamon (Cinnamomum verum or C. zeylanicum) is a small evergreen tree, prized for its fragrant, sweet-spicy bark. Cinnamon has a long history of use in traditional medicine in China, India and Persia, where it was thought to help inflammation, nerve pain, heart disease and cough (NCCIH). NCCIH says research doesn't clearly support cinnamon for any health condition, and it is unclear whether it helps diabetes.

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. 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.'

Lavender (Lavandula officinalis, also known as L. angustifolia) is a small, perennial shrub that can grow about 3 ft (1 m) high, characterized by its narrow, silver-green leaves and spiked violet-blue flowers. Renowned for its sweet aroma, lavender has a long history in traditional medicine for improving mood and sleep, and NCCIH says it is promoted today for calming anxiety and stress. NCCIH says studies suggest an oral lavender oil product might help anxiety, but more high-quality research is needed to reach reliable conclusions.
