Milk thistle is an old traditional remedy that is known for its stimulating properties on the body. When your body is being attacked by itself, as happens in the case of Addison’s disease, you need to stimulate the immune system to defend itself, and the rest of your organs and systems. Milk thistle can effectively counter the symptoms of Addison’s Disease by stimulating the production of hormones so your body can function normally. However, this should be considered a complementary treatment, and for most cases of Addison’s Disease, professional and formal treatment is required.
