Manjakani is a truly miraculous herbal medicine. Actually, it is not a herb in itself, but the product of oak trees when wasps injure their leaves.

In Indonesia, and to a lesser extent in Malaysia and the Philippines, manjakani is used by women to restore the elasticity of the vaginal wall, especially after giving birth.

Restoring the elasticity of the vaginal wall primarily means to contract it. It is the same effect that Western women try to achieve with vaginal canal reduction surgery, but it is much more benevolent. Sure, surgery can reduce the size of the vaginal canal, but recuperation after surgery takes many months, and the feeling men have in an "operated" vagina is not pleasant because the scars do not lubricate.

Manjakani does not have this negative side effect. Indonesian women take it to contract the vaginal canal, in the same way one feels one's mouth contracting when drinking a very dry wine. The skin just wrinkles and contracts.
