Proper nutrition, as always, can go a long way to ensuring an adequate source of these nutrients. Chinese medicine has a valuable comment to make on fatigue, and regards it as a deficiency. Acupuncture treats stress-related fatigue by choosing certain acupuncture points to tonify the adrenal glands. Interestingly, acupuncture points will often be chosen on the kidney meridian to treat this type fatigue. Astragalus is a particularly interesting medicinal plant whose use is not restricted to treating fatigue.
Astragalus has an immune stimulating effect.
Many of the Chinese medicine formulae that are used to prevent recurring upper respiratory infections feature astragalus as one of the main ingredients. Fatigue is perhaps an underrated condition. In some ways fatigue can be seen as a warning signal that is telling us to slow down and start taking better care of our bodies. There may be different ways to approach the topic, but perhaps it's best to regard fatigue as an imbalance in your physical or emotional life. The goal of treatment, then, is to restore the normal equilibrium and let fatigue give way to life and vigor.
