Indian Borage, also known as Mexican Mint or Cuban Oregano, is an aromatic herbaceous perennial (Plectranthus amboinicus). Its fragrant leaves are valued across cultures, making it a popular addition to gardens and homes.
Identifying Indian Borage
Indian Borage is characterized by its thick, fleshy leaves, which have a velvety, fuzzy texture. These ovate leaves are typically green, sometimes with a white outline on variegated forms, and feature scalloped or toothed edges. The plant is semi-succulent, with fleshy stems that can become semi-woody with maturity. A key identifying feature is the strong, pungent aroma released when the leaves are crushed, due to essential oils like carvacrol and thymol.
Growing Indian Borage
Indian Borage is relatively easy to cultivate, thriving in full sun to partial shade. In hotter climates, afternoon shade can prevent leaf burn. Well-draining soil is ideal, as the plant is susceptible to root rot if waterlogged. It tolerates various soil types, but amending with inorganic materials can improve drainage.
Watering needs are moderate; as a semi-succulent, Indian Borage stores water in its fleshy stems and leaves. Allow the soil to dry completely between waterings to prevent overwatering. This plant prefers warm climates and is sensitive to frost, making it an annual in cooler regions or a perennial in tropical and subtropical zones. In frost-prone areas, it can be grown in containers and brought indoors.
Propagation is straightforward, primarily through stem cuttings. Cuttings of about 15 cm with a few leaves root readily when inserted into moist, well-draining soil after removing lower leaves. While rooting in water is possible, planting directly into soil is often recommended to avoid rot. Regular pruning encourages bushier growth and more leaf production.
Culinary Uses of Indian Borage Leaves
Indian Borage leaves have a distinct flavor profile, often described as a blend of oregano, thyme, and mint, with notes of citrus or a peppery taste. This robust flavor means the herb is typically used in moderation to avoid overpowering other ingredients. Young leaves are often preferred for fresh use due to their softer texture.
They can be incorporated into stuffings, soups, and stews, and pair well with meats like fish, lamb, and poultry, or in vegetable dishes. It is also used to make teas or infusions, and can be added to pesto as a flavorful alternative to basil. For preparation, leaves can be chopped finely or battered and deep-fried to create fritters, offering a unique texture and flavor.
Traditional and Medicinal Uses of Indian Borage Leaves
Indian Borage has a long history of use in traditional medicine systems across Asia, Africa, and the Caribbean. Traditionally, its leaves address various ailments, primarily respiratory conditions like coughs, colds, sore throats, nasal congestion, asthma, and bronchitis, often prepared as a tea or by chewing raw leaves. Its compounds are believed to act as expectorants, helping to clear mucus and phlegm.
Beyond respiratory issues, it has been traditionally employed for digestive complaints such as indigestion, flatulence, colic, and diarrhea. Topical applications of crushed leaves or poultices have been used for skin conditions, including burns, sores, insect bites, stings, and eczema, and to reduce inflammation and pain. Traditional uses also extend to fever reduction, headache relief, and promoting relaxation.
These are historical and traditional uses, and their efficacy is not always supported by extensive scientific evidence or medical consensus.

Always consult a qualified healthcare professional before using Indian Borage or any herbal remedy, especially if you have existing health conditions, are pregnant, nursing, or taking medications.
Important Considerations and Safety
Harvesting Indian Borage leaves can be done continuously using a “cut-and-come-again” method, which encourages bushier growth. Young, tender leaves are often preferred for consumption. While generally considered safe for culinary and traditional uses, some individuals might experience a burning sensation in the tongue or esophagus when consuming the leaf juice. Moderation is advisable when using any herb. Pregnant women, those who are breastfeeding, or individuals on medication should consult a healthcare professional before consuming Indian Borage.
