I've been told that the following are good for treating your adrenals:
Vitamin B-Complex (yeast free)
You can buy a liquorice tincture with siberian ginseng (must be siberian) or a liquroice tincture, you should take 30 drops a day for a month. Alternatively buy some organic liquorice tea and drink 2 cups a day (this isn't as strong and will therefore take longer and I couldn't bear the taste either!)
Oats are good because of the slow release thing, you can also get this in tincture though. I'm treating mine at the moment and also taking a yeast free vitamin B complex which is something your system will be lacking in if your adrenals are exhausted.
Try to avoid any stressful situations- stress is just making them work harder, plenty of time out. I've been on this for 2 weeks now and it is DEFINITELY working.
