guru chandal plant

[acereeta]

Is there any plant, tree or root etc. called guru chandal?

 

I have heard that there is a yoga called guruchandal yoga, but

I would like to know if there is a plant by that name.

 

If yes, then where can i find it in Calcutta, India and is there any other

name by which that plant is called?

 

Thanks for helping,
