Take adaptogenic herbs the best of which is probably Rosavin . Ginseng III may also be of great value. All of these adaptogens prevent excess cortisol which is why they are honored for their longevity value. Allied with the cortisol problem is the problem of producing the wrong kinds of eicosanoids. The good ones are anti-inflammatory, prevent cancer by stopping cellular proliferation, bolster the immune system and protect the blood vessels by preventing abnormal clotting and constriction of the arteries.
Bad ones do the opposite.
Such Omega-6's are rich in our diet since they are the primary component of polyunsaturated cooking oils. A host of disease are caused by eicosanoid imbalances including heart disease and high blood pressure, type 2 diabetes, various inflammatory and autoimmune diseases, cancer and depression. These are aging diseases which suggests that as we age the eicosanoid ratio gets unbalanced. It doesn't have to be, though. The good eicosanoids are created when Omega-3 EFA's intercept the production line and steer it to the good ones.
