Evening Primrose (Oenothera biennis)

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.

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.

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.

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.

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. Native Americans used the root for a variety of conditions, including menstrual cramps, kidney ailments and sore throat; NCCIH says research has focused on menopause symptoms, and there aren't enough reliable data on other uses.

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.
