Is Kushta Roga in Ayurveda Curable? - #12436

I don’t know how to explain this properly but my younger brother, who is 24, has been struggling with some weird skin issues for almost 3 years now. At first, we thought it was just an allergy or an infection, but no medicine has helped. The doctors say it’s some chronic skin disease, but no one is giving us a clear answer. Some call it psoriasis, some say eczema, but my brother's condition doesn’t fit either perfectly. We live in a village, and my family prefers Ayurveda for treatment. My grandmother told us that it might be kushta roga in Ayurveda, but we don’t really understand what that means. She said kushta roga in Ayurveda is not just one disease, it can be many different types. Some people say it comes from “impure blood,” some say it’s because of food, and others believe it’s a past-life karma issue. We went to a local Ayurvedic doctor who said my brother might have “Vata-Pitta Kushta.” He suggested some herbal medicines, like neem, haritaki, and manjistha. He also told us to avoid curd, salt, and spicy food. But after using these medicines for 4 months, there’s no major change. The itching is a little less, but the red patches on his back, arms, and neck are still spreading. The worst part is that he gets small cracks on his skin that sometimes bleed. Now we are really confused. Is kushta roga in Ayurveda something that can actually be cured, or is it like those diseases that just keep coming back? Is there a stronger treatment that works faster? Some people say Panchakarma is the best way to treat kushta roga in Ayurveda, but is it safe? I also read that some cases require detoxification before herbs start working properly—how do we know if that’s necessary? Please help, any advice will be really appreciated. Has anyone else faced this? If you’ve tried any Ayurvedic treatment for kushta roga in Ayurveda, did it actually work? Or should we try some different approach?
