the tree is quite big, it is tall about 10 m ,the body of tree is about your legs size. Lao people cut the twig and burn it until it becomes a bit yellow or black and then boil it for quite long time and then serve to the women who just give birth to a baby to drink. the women will feel like full of milk in the breasts and this herb is really helping the women to increase the Milk. thats why Lao women don't worry about their milk after giving birth a baby.
