Herbs and Supplements can be very helpful, especially when you have no choice but to take on the care of yourself. They can be very costly, and unfortunately you have to try many before you find what is most important for you. CFS clinics may provıde a list, such as this one:

However, what I have found most helpful is Valerian for nerves, L-Theanine for mood plus (both may be taken together on an 'as needed' basis); hot shower on the base of the neck, cold on inflammed areas such as the top of the head; Siberian or other Ginseng for energy (taken before leaving the house on an outing for example); non-soy or egg Protein powder (whey/rice) for general energy stability; Vitamin D3 large dose daily; super digestive enzymes along with careful diet (gluten free and high protein recommended). allergy prevention (neti pot, herbal steam inhaler, etc). A dark pair of sunglasses and darkening bedroom curtains, using less unnatural light while providing as much natural light as can be tolerated is helpful. Using ear muffs and mask for sleeping, blue blocking glasses in the evening before bed can help sleep issues. Melatonin was helpful but not completely and had to be increased too much until the blue blockers caused my sleep to return after decades of hover-sleeping.
Everyone is different so it has to be customized to the individual's particular symptoms and needs starting with the worst symptoms to the lesser.
