"Ever heard people in Asia and South America did whenever they are getting sick ?
For people live quite far from Hospital or Doctor, they usually treated by using Herbal Medicine. The plant itself is taken from the forest. They know which medicinal plant to use for each kind of disease.
How do they know which plant is good for some specific disease ?........Their ancestor used that kind of plant since hundreds or maybe thousand years ago. Yes..that is the answer.
In some countries, people use Gotu Kola (Centella asiatica) for wound-healing. Later, Scientist found that the active constituent of Centella asiatica is Asiaticoside. Asiaticoside is clinically-proven to be used for wound-healing. Some pharmaceutical products are made from Centella asiatica.
