Vasculitis. .
You said it’s the kind of microcirculatory disease that is said to be basically incurable by Chinese and Western medicine, where the blood doesn’t flow or something? I heard it's quite difficult to treat. .
My family works in a copying company, and an uncle came to my house to make application materials, apply for national patents, etc., sprays to improve microcirculation and the like. It seems pretty powerful.
I heard him say that people in Russia often suffer from this disease. He accepted a Russian patient. The patient didn't believe it, so he treated him for free. The Russian ran away after he recovered. The uncle paid a lot of money himself.
Do you want to ask him? I should be able to find his contact number if I look for it.
