Oregano
Oregano (US: , UK: ; Origanum vulgare) is a flowering plant in the mint family (Lamiaceae). It is native to temperate Western and Southwestern Eurasia and the Mediterranean region.
Oregano is a perennial herb, growing from 20–80 cm (7.9–31.5 in) tall, with opposite leaves 1–4 cm (0.39–1.57 in) long. The flowers are purple, 3–4 mm (0.12–0.16 in) long, produced in erect spikes. It is sometimes called wild marjoram, and its close relative, O. majorana, is known as sweet marjoram.
Ajwain
Ajwain, ajowan (), or Trachyspermum ammi—also known as ajowan caraway, bishop’s weed, or carom—is an annual herb in the family Apiaceae (or Umbelliferae). Both the leaves and the seed‑like fruit (often mistakenly called seeds) of the plant are consumed by humans. The name “bishop’s weed” also is a common name for other plants. The “seed” (i.e., the fruit) is often confused with lovage “seed”.
