Tamarindus indica, also known as tamarind, tamarind or imli (in India), is an evergreen to semi-evergreen tropical tree from the legume family with sour, sweet-sour legumes.

Origin

• Originally from tropical Africa (especially East and West Africa, such as Sudan, Nigeria, Kenya, Ethiopia).
• The name “tamarind” comes from the Persian “tamar-i-hind” (Indian date); in Sanskrit “Amlika” → indicates ancient presence in India.
• Grows naturally in dry savannahs, moist valleys, along rivers and coastal areas in well-drained, poor to fertile soils; adapted to drought and heat.

Care

• Grows as a tree up to 20 meters high with a broad crown and thick trunk; Slowly growing in youth, later faster.
• Prefers full sun , tolerates heat and warmth excellently.
• Plant in well-drained, fertile to poor soil (sandy-loamy, pH 6.0–7.5); tolerates saline, calcareous or poor soils; Add organic matter for better growth.
• Watering: regularly during settlement; moderate thereafter (very drought tolerant if established); Keep the soil slightly moist, but no waterlogging (root rot risk).
• Winter hardiness: limited (USDA zones 9b–11); tolerates light frost up to about -5 to -8 °C for a short time; in colder climates (such as the Netherlands/Belgium) grow as a container plant and overwinter frost-free (min. 5–10 °C, light spot indoors).
• Fertilization: manure balanced in the growing season (spring/summer); do not over-fertilize; nitrogen-fixing via root nodules.
• Pruning: minimal; light shaping in spring or after fruiting; The tree tolerates heavy pruning well.

Usage

• Culinary applications: pulp of the pods (sweet-sour) in sauces (such as Worcestershire sauce), chutneys, curries, sambar, soups, lemonades, candy, jam, syrup and drinks; young leaves and flowers edible in salads or curries.
• Medicinal/Traditional: laxative (against constipation), digestive stimulant, fever-reducer, anti-inflammatory, antimicrobial; used for stomach upset, diarrhea, dysentery, wounds, malaria, cough, diabetes, high blood pressure, skin problems and as an antioxidant; in Ayurveda, TCM and African folk medicine.
• Nutritional value: rich in vitamin C, B vitamins, iron, potassium, magnesium, fiber and antioxidants; Pulp contains a lot of organic acids (such as tartaric acid).
