Scutellaria is a genus of flowering plants in the mint family, Lamiaceae. It contains about 300 species, which are commonly known as skullcaps.[2] The generic name is derived from the Latin word scutella, meaning "a small dish," referring to the shape of the calyx.[3]

Ocimum tenuiflorum, Holy Basil (also tulsi, tulasī), is an aromatic plant in the family Lamiaceae which is native throughout the Old World tropics and widespread as a cultivated plant and an escaped weed.[1] It is an erect, much branched subshrub, 30–60 cm tall with hairy stems and simple, opposite, green leaves that are strongly scented. Leaves have petioles, and are ovate, up to 5 cm long, usually slightly toothed.

Nettles constitute between 24 and 39 species of flowering plants of the genus Urtica in the family Urticaceae, with a cosmopolitan though mainly temperate distribution. They are mostly herbaceous perennial plants, but some are annual and a few are shrubby. Most of the species have stinging hairs on the stems and leaves.
