Just made a small study on Justicia betonica in Kannada and Kodavas
- There is no such word aati in any of the Kannada dictionaries I refered.
- Kodavas use Kannada words while speaking in their language. Based on that I think.
Madd means Medicinal ) (In Kannada its Madd, (Madh), Maddu, )
- (Tokku ) Soppu (meaning Green leaves)
So, Madd Tokku translates to Medicinal green leaves. Not the exact species.
Justicia Betonica is indeed a medicinal plant as per the link you have mentioned.
Here is a link, frlht mentions Betonica justicia as Kaadu kanakambara. (Forest(Wild) crossandra.
