Question 1

What is Higurala in Sri Lanka?

Accepted Answer

Higurala is the Sinhala common name for Dioscorea alata, a species of tropical yam widely cultivated and consumed in Sri Lanka. The tuber can have white, cream, or purple flesh depending on the variety, and it is used in both savoury curries and sweet preparations.

Question 2

Is Higurala the same as purple yam?

Accepted Answer

Dioscorea alata is commonly called the purple yam in many parts of the world, though not all varieties have purple flesh — some are white or pale. In Sri Lanka, the name Higurala refers to the species as a whole, regardless of flesh colour.

Question 3

What gives some Higurala its purple colour?

Accepted Answer

The purple flesh of some Higurala varieties comes from anthocyanins, natural plant pigments. Other varieties have white or pale flesh. The tuber also contains complex carbohydrates, dietary fibre, potassium, vitamin C, and B vitamins.

Question 4

How do you cook Higurala?

Accepted Answer

The most common method is to peel, cube, and boil the tuber in salted water until tender. It can also be cooked in coconut milk as a curry, stir-fried with onion and spices, or mashed into sweet puddings when using purple-fleshed varieties. It does not require soaking before cooking.

Question 5

Where does Dioscorea alata grow naturally?

Accepted Answer

Dioscorea alata is native to tropical Asia and thrives in the edges and canopy gaps of rainforests and secondary woodlands. In Sri Lanka it grows most readily in the wet lowland zones of the south-west, and is also widely cultivated in home gardens across the island's intermediate zone.

Question 6

Can I buy Higurala in Sri Lanka as a visitor?

Accepted Answer

Yes. Fresh Higurala tubers are sold in local markets throughout the wet zone and up-country regions, typically alongside other root vegetables. Dried or processed Higurala products are sometimes available in Ayurvedic shops in Colombo and Kandy.

Question 7

Is Higurala part of Sri Lanka's Ayurvedic heritage?

Accepted Answer

Yes. Higurala has a long place in Sri Lanka's Ayurvedic and hela wedakama heritage, and is sometimes included in traditional preparations alongside other botanicals. This describes cultural tradition, not medical advice; consult a qualified doctor about any health condition.
