Bharangi is a very old herb in Ayurveda which is famous for helping to restore the health of the lungs and to give good swara (rhythm or sound) to your voice. This in turn gives you better courage.
Bharangi is classified as a divya aushadhi (divine herb) and requires a good vibrational environment to thrive. With the encroachment of modern life on the forests of India today, bharangi has become a rare sighting. In fact, a lot of controversy has come up in the modern dravya guna texts regarding bharangi. Some say it is a tree, others say it is a bush and everyone claims to have the real bharangi.
