In human cancer, reduced appetite and weight loss are serious symptoms and are difficult to manage. These symptoms not only effect the quality of life, but also reduce the tolerance and response to anti-cancer drugs, thereby effecting the prognosis and survival to disease. These symptoms are caused, among others, by overactive immune system of the body. Anti-cancer drugs that were effective in the beginning start losing their efficacy, and are less tolerated. Also in autoimmune diseases, the immune system is overreacting. This herbal invention, based on Artemisia species, ginger root and large cardamom, each targeting at different factors involved in weight loss and autoimmune diseases, is effective in improving appetite, thus counteracts the development of resistance to anti-cancer drugs, and helps in the cure of autoimmune diseases, IgA-Nephropathy, which has no cure so far.
