Did you know this plant is also a traditional medicinal which is showing great promise in current medical research? I stumbled upon the medical info by Googling the plant just to learn more about it.
Research study results about the anxiolytic efficacy of extracts from this plant have been very encouraging so far- results were comparable to the antianxiety drug lorazepam, but with less patient complaints (it is better tolerated).

Traditionally used among some Mexicans as a herbal nerve tonic, which is how it ended up being studied further.

Amazing! No I didn’t know that this beauty has been used as a nerve tonic. Isn’t it fascinating how plants can be so beneficial in treating various medical problems, but so much of this knowledge has been lost over the generations. Sounds like this plant might be very very beneficial.
