I have a prescription of traditional Chinese medicine for treating white hair. Please help me have a look.

Your prescription is very general, but there are many medicines and few medicines. I'll change it for you: 5 Jin of wine.

Rehmannia glutinosa 200 restraint Polygonum multiflorum 200 g Lycium barbarum 50 g Astragalus 30 g Cistanche deserticola 30 g Glycyrrhiza 30 g

Radix Rehmanniae Preparata, Radix Polygoni Multiflori and Fructus Lycii can nourish liver and kidney and blacken hair. It is enough to treat qi deficiency and astragalus, and it is enough to treat weak constipation and cistanche deserticola, and then it is reconciled with licorice. Small in number but powerful.
