Question 1

What is Macrotyloma uniflorum used for in Ayurveda?

Accepted Answer

In Ayurvedic medicine, Macrotyloma uniflorum is used primarily for its digestive, diuretic, and metabolic-supporting properties. Traditional practitioners prepare it as a decoction or powder to address urinary concerns, sluggish digestion, and conditions associated with excess kapha dosha. It is considered warming in potency and light in quality within the classical Ayurvedic framework.

Question 2

What is horse gram called in Sinhala?

In Sinhala, Macrotyloma uniflorum is known as kollu (කොල්ලු). The name is widely recognised across Sri Lanka, where the seed is used both as an everyday food ingredient and in traditional medicinal preparations.

Question 3

Is horse gram good for kidney stones?

Accepted Answer

Traditional Ayurvedic texts and some preliminary scientific studies suggest that horse gram may have properties relevant to urinary health, including potential benefits in managing kidney stones. However, clinical evidence in humans remains limited. Anyone with a kidney condition should consult a qualified medical or Ayurvedic practitioner before using it therapeutically.

Question 4

Can you eat Macrotyloma uniflorum every day?

Accepted Answer

Horse gram is commonly eaten as a regular dietary pulse in Sri Lanka and parts of South India, typically as a cooked dish or thick curry. Ayurvedic guidance suggests that its hot and dry qualities make it more appropriate for people with a cooler, damper constitution, and overconsumption may not suit individuals with a pitta-dominant constitution or certain digestive sensitivities.

Question 5

Where is horse gram grown in Sri Lanka?

Accepted Answer

Macrotyloma uniflorum is cultivated mainly in Sri Lanka's dry zone — particularly in the North Central, Northern, and Eastern provinces. Its drought tolerance makes it well suited to regions with distinct dry seasons and sandy or loamy soils. It is also found in disturbed or semi-wild habitats across the intermediate zone.

Question 6

What does horse gram look like?

Accepted Answer

Horse gram is a small, annual herb with trifoliate leaves and pale yellow flowers. Its seeds are flat and oval, typically reddish-brown, dark brown, or near black in colour, and noticeably smaller than most common lentils or beans. The seed pods are thin and elongated, each containing several seeds.

Question 7

Is Macrotyloma uniflorum part of Sri Lanka's official Ayurvedic pharmacopoeia?

Accepted Answer

Yes. Macrotyloma uniflorum is catalogued within Sri Lanka's formally recognised Ayurvedic medicinal plant system, overseen by the Department of Ayurveda. It is listed alongside other indigenous and naturalised plants that have documented therapeutic applications within the island's traditional medicine tradition.
