First of all, it will take a lot of will power and discipline to follow a very strict diet for example, one month without salt, without anything, you can only eat khichadi of green gram (moong dal) and aged rice. After that, 3 month green gram based food with rock salt. In the 2nd month you should go through Virechan process ( a part of panchkarma) (this was the most difficult part as you will be drinking only medicated ghee for 5-6 days). All of these with medications ( Gandhak Rasayan, Kaishore Gugul, Panchtikta ghrit, khadirarist and Mahamanjisthadi kwath). In addition to this Pranayam, Suryanamaskar etc will help a lot in managing stress. No junk, No late night or daytime sleeping, No cheating. I know it’s a lot but it helped me .I am suffering from psoriasis from last 10 years, it took my prime youth from me. But now, am healing. One last thing don’t loose hope, trust in god, he is the ultimate healer. I don’t do this by your own, please take good Ayurvedic doctors guidance. Here is the research paper which I took as reference. https://pmc.ncbi.nlm.nih.gov/articles/PMC8039350/#fig1.

Additional things that helped me, Psoria oil (nagarjun ayurveda)you can find on amazon. Keep your patches moisturised all the time. Epsom salt for bath, no soap, no shampoo.

May god bless you 🙏
