Ginger is massive adaptogen as well as general superfood that does many other amazing things. It’s also one of the most economical adaptogens! It’s GRAS for children & adults - only contraindication is some medications such as blood thinners.
There are numerous past posts here on the forum about it, if you use the search bar.
Parsley is also fabulous for adrenal support, and very economical. Longstanding history of usage in western herbalism.
Last but NOT least - organ meats have micronutrients such as B vitamins that are amazing for combating fatigue and raising energy. I take grassfed beef liver capsules several times a week. Our ancestors ate meat nose-to-tail, which meant plenty of collagen and micronutrients. Grassfed chicken & lamb livers are also good for Bs.
