First, let's talk about functions. This formula has a certain effect on black hair and is very supple. But be careful that your spleen and stomach can digest such medicine. So if you eat it specifically, you can eat it twice a day, 3 grams each time, once in the morning and once in the evening. It's safe and there will be no side effects.

And the specific ratio is as follows: Rehmannia glutinosa 20. Polygonum multiflorum Thunb 15. Eclipta prostrata 10. Black beans 15. Ligustrum lucidum 10. Black sesame 10. Black mulberry 10. Can be matched according to this ratio. My suggestion is that "raw licorice 5" can be added when stirring to play a role in neutralization and offset.

Farewell.
