Question 1

What is Wel Keppetiya used for in traditional medicine?

Accepted Answer

Wel Keppetiya (Croton aromaticus) is used in Sri Lankan Ayurveda to treat bronchitis, diarrhoea, dysentery, fever, and malaria. The roots, bark, and leaves are each prepared in different ways depending on the condition. It is typically administered as a decoction or compound preparation by qualified practitioners of indigenous medicine.

Question 2

Where does Croton aromaticus grow in Sri Lanka?

Accepted Answer

The plant is found in open scrubland, forest margins, and disturbed vegetation across Sri Lanka's dry and intermediate zones. It is not typically associated with the high-elevation wet zone or montane forests. Its resilience in secondary habitats means it is relatively widespread, and it is sometimes cultivated in home gardens.

Question 3

Is Croton aromaticus the same as ornamental Croton plants?

Accepted Answer

No. Croton aromaticus is a wild, medicinally significant shrub native to the Indian subcontinent, whereas most ornamental Croton plants sold for gardens are cultivars of Codiaeum variegatum or other Croton species bred for colourful foliage. They share the same genus but differ substantially in appearance and use.

Question 4

Does Croton aromaticus have any scientific backing for its medicinal uses?

Accepted Answer

Laboratory research on Croton aromaticus extracts has demonstrated insecticidal and fungicidal activity, lending some scientific support to traditional claims. However, rigorous clinical trials in humans are limited. Anyone considering using the plant medicinally should consult a licensed Ayurvedic physician.

Question 5

How tall does Croton aromaticus grow?

Accepted Answer

Croton aromaticus typically grows as a woody shrub reaching up to around 3 metres in height. Growth rate and ultimate size depend on soil quality, moisture availability, and light conditions. In cultivation, it can be pruned to remain smaller.

Question 6

Is Croton aromaticus endemic to Sri Lanka?

Accepted Answer

No, it is not endemic to Sri Lanka. The plant is native to the broader Indian subcontinent and occurs across several South Asian countries. Sri Lanka is, however, within its natural range, and the plant has a well-documented history of local use in Ayurvedic medicine on the island.

Question 7

What family does Croton aromaticus belong to?

Accepted Answer

Croton aromaticus belongs to the family Euphorbiaceae, one of the largest families of flowering plants in the world. This family also includes economically important plants such as rubber trees, cassava, and castor oil plants, many of which have significant traditional medicinal or industrial uses.
