Ngoc Cau mushroom (Cynomorium songaricum Rupr) grow abundantly in the forests of Khau Tinh (Na Hang).

According to statistics, the whole commune currently has over 200 types of medicinal herbs, all of which are precious remedies.

That is why the Dao people in Khau Tinh have kept the "secrets" of traditional medicine for generations.

In addition to exploring medical herbs in the forest, many people also take the initiative to plant medicinal plants in their gardens to treat common respiratory and digestive diseases at home, which is also a way to preserve and conserve precious medicinal plants, saving a lot of time going up the mountain to collect medicinal plants.

Especially, local people have a tacit agreement to only exploit according to demand, not to exploit massively and also not to collect medicinal plants if not necessary.

Mr. Duong Van Cuong, Head of Phia Phoong Forest Protection Station, shared that there are few places where people are as conscious of forest protection as here.

In addition to tacit agreements on using medicinal plants effectively and according to requirements, people are also conscious of regenerating the tree source.

In particular, when going to collect medicinal plants, people are also real forest patrollers, promptly supporting local authorities when necessary, he shared.
