Low-dose Naltrexone, better known as LDN, is a recent addition to the repertoire of autoimmune patients. The claim is that it “can normalize the immune system”. There is an extensive page of information found here which catalogs the list of diseases for which it has been useful.
I wanted to know exactly how it works, but it turns out that the best we can do is know “how it is BELIEVED to work”.
In general, in people with diseases that are partially or largely triggered by a deficiency of endorphins (including cancer and autoimmune diseases), or are accelerated by a deficiency of endorphins (such as HIV/AIDS), restoration of the body’s normal production of endorphins is the major therapeutic action of LDN.
