Why idlis were once made on these medicinal leaves

A humble tree, often found in Kerala home backyards, with flowers that look like hibiscus. For many youngsters, 'Poovarassu' or the 'Portia tree' is nothing more than that. However, the tree, with the scientific name Thespesia Populnea,' has numerous medicinal benefits, roots to leaves. Ayurveda describes its bark as 'verinmel tholi' and uses it to treat certain diseases.

The tree is most often found in coastal areas and along riverbanks, as it acts as a natural windbreaker. The tree spreads out its branches after growing up to 10 metres. The rose-and-white flowers with hints of yellow are also known as Indian tulips. The fruits hang from the stalks, and the fresh leaves are greyish in colour. Termites do not attack the poovarassu tree, which blooms year-round.

Why were idlis made on them
In the past, idlis were made on these medicinal leaves by pouring batter on them and steaming them. According to Dr Sreelatha Chandroth of the Government Ayurveda College, Kannur, this was probably because 'poovarassu' has properties that can heal our digestive distress.

Its bark and fruit are also used in various ayurvedic decoctions. Poovarassu is an important ingredient in Ayurvedic medicines for blood purification and excessive bleeding, as well as for treating conditions such as skin infections, scabies, psoriasis, ringworm, vitiligo, and leprosy. Besides, various parts of this plant could be used in medicines for wounds, lesions, diabetes, diarrhoea, white discharge in women and even liver diseases. Herbal oil is extracted from the bark and is also used in Ayurvedic decoctions.
