The traditional Chinese medicine practitioner said so
This prescription can cure most skin diseases.
There is a psoriasis patient in his forties who sat down in my clinic and rolled up his sleeves to expose the skin on his arms. I saw red patches on his forearms and arms, covered with a thick layer of silver white scales. He couldn't help but scratch them with his hands.
I gently touched the swollen areas with my fingers, and the skin felt rough with some scales peeling off from the edges.
I asked him, 'How long has this situation been going on?'
He replied, "It's been six months now. At first, there were a few small spots, but they gradually spread and became more and more severe. The itching is unbearable for me, and I can't sleep at night
I prescribed medication for him, and he came for a follow-up visit a week later. The redness and swelling on his arm were greatly reduced, and the scales became noticeably thinner.
He happily said to me, "Dr. Fu, thank you! After you treated me, my itchiness has decreased a lot, and I can finally sleep a whole night
Source of prescription
The prescription I prescribed comes from the "Experience Album of Difficult and Critical Illnesses" by Li Ke, a traditional Chinese medicine practitioner known as the "Thunderbolt Doctor".
When treating skin diseases for the first time, Li Lao collected many topical formulas to reduce inflammation and itching. Although they were effective, most of them only healed and relapsed, causing the condition to recur repeatedly. Therefore, he sighed: seeing the skin heal the skin, there will never be a healing period.
Having gone through the stage of treating the skin, Li Lao believes that although skin diseases occur in the skin limbs, they are closely related to internal organs and emotional changes, as well as the imbalance of qi and blood.
So the way to treat skin should focus on the whole, starting from regulating the qi and blood of the five organs.
Li Lao kept trying and summarizing his experience, finally breaking through the fog and breaking free from the vicious cycle of various skin diseases, and developed this wonderful prescription.
Li Lao wrote in his works that this prescription can treat 15 stubborn skin diseases, including goosefoot wind, psoriasis, neurodermatitis, tinea versicolor, vitiligo, warts, penicillin allergic dermatitis, allergic eczema, yellow water sores, alopecia areata, skin scratch syndrome, ulcers, hypersensitive purpura, melasma, localized dermatomyositis, etc.
