Thaneer vittan kizhangu (Tml),
It was traditionally known as a medicinal plant, but people lost the practice. In ayurveda it is a medicine of great value. And based on those details people have restarted using it.
The milk decoction (by adding crushed peices of the root in a mixture on one glass of milk and one glass of water and boiling it till all the water evaporates) is taken. In families where the milk is unaffordable, just a decoction in water is taken.
Eashwaramma says that this works better than all the purchased ayurvedic medicines ! That is as per the ayurvedic text - that drugs growing wild are always far more potent.
Every time in the village we go on a trip down the stream for shatavari. While walking down when I mentioned to Eashwaramma that with so many people using it, there would be less and less, she simply asked, 'let everyone use - should only we benefit ?'
