Culinary
herbs are essential part of cooking traditions across the world for thousands
of years. From modest home kitchens to professional restaurants, they play a
vital role in transforming ordinary foods into delicious and memorable dishes.
Beyond taste, these herbs also offer nutritional and medicinal benefits to
humans. A substantial proportion of the world’s population depends on
traditional medicine for primary healthcare even today. Among the many culinary
medicinal plants used across different cultures, Indian borage holds a special
place due to its aromatic nature and therapeutic properties. Botanically known

Indian

Yemen. Through cultivation and trade, it spread to tropical and subtropical
regions around the world. In India, it is commonly cultivated in kitchen
gardens for medicinal and culinary purposes in southern states.
MORPHOLOGICAL
CHARACTERISTICS
Indian borage is a perennial, succulent, aromatic herb that typically grows to a height of up to 50 cm (or sometimes more in most suitable conditions). The plant has thick, fleshy hairy, and branched stems. The leaves are thick, succulent, broad, and oval. They are strongly aromatic and are covered with delicate hairs. The flowers are small, tubular, and pale purple in colour. The flowers are arranged in clusters and usually appear during spring and summer.
Indian
borage grows well in tropical and subtropical climates and requires minimal
care. It is propagated through stem cuttings, which root easily in moist soil.
Due to its fast growth and minimal maintenance, it is an ideal herb for home
gardens and pots. It requires well‑drained and fertile soil and partial
sunlight to full sun for its optimal growth.
Indian borage owes its
medicinal benefits to the abundance of phytochemicals it contains. Scientific
studies have identified several bioactive compounds, including: thymol (antimicrobial,
antiseptic), carvacrol (antifungal, antibacterial), α-humulene, undecanal,
γ-terpinene, p-cymene, caryophyllene, 1,8-cineole, eugenol (anti‑inflammatory,
analgesic), α-terpineol, α-pinene, β-pinene, β-selinene, flavonoids (antioxidant),
tannins (astringent, wound healing), and phenolic compounds (antioxidant, anti‑inflammatory)
in its leaves.
Indian
borage or Ajwain patta is frequently used as a culinary herb across the world over
due to its oregano‑like aroma that makes it a popular seasoning herb for
