"Take the recommended dose of the adaptogen you have chosen every day for a minimum of two weeks, carefully monitoring for changes in mood and in how you feel. These herbs are most effective when taken on an empty stomach. Maimes suggests that you take rhodiola in the morning, while holy basil, eleuthero, schisandra, ginseng and astragalus should be ingested during the day. Cordyceps, reishi, ashwagandha as well as teas made with holy basil and jiaogulan can be taken day or night. If after two weeks no changes have been noted, discontinue for a few days and evaluate any changes."

Kid#2: Still sick now despite being treated for years but doing better (not well yet).
Kid#3: Generally good but relapsing off/on.
Me: Adv Labs positive 2016 (suspected I passed to my kids)-not as sick as others, mostly battling fatigue and yeast issues (heart/kidney issues resolved)
Treating with herbals now.
