I am new to this site. I am a caretaker of my husband who has PSC. He has had it for about 6 years and monthly has had flu like symptoms which his GI tells him is part of PSC. When he gets these flu like symptoms, he is very fatigued, runs a temp of about 103, and he does not eat. It usually last about 24 hours. He was getting them every month almost to the hour. I started lemon water with him. He has 1/2 lemon juiced into a glass of water everyday. His symptoms have gone and his liver enzyme counts have been cut in half. In fact, all his numbers from blood work for PSC have been cut in half. He has not had flu like symptoms in about 5 months. I have no idea if it is the lemon water, but i think it is. I just wanted to share this with everyone. It sure would not hurt to try it since is all natural.
