To me, cortisol is high because the body is upregulated to handle/need more, either because the feedback loop is starting to get more worn/damaged, or because something is constantly stimulating the LHPA axis because of parasites, infections, toxicity etc.
It seems to me that ARL is further speeding up overworked adrenals and just upregulating and damaging things even further.
Usually, the idea is to blunt high cortisol with phosphatidylserine or something else herbal. Personally, my body is so weak now that contaminants in PS harm my tissues, plus if there's something overstimulating my HPA axis, it just seems to counter the lowering herbs.
