To treat chronic fatigue syndrome, it is a misconception to solely rely on ginseng for anti-fatigue purposes, because prolonged use of ginseng can easily cause internal heat. Nowadays, many famous athletes take "Five Gods Decoction" which does not contain ginseng, deer antler or other tonic medicines. Instead, it is made up of fourteen special Chinese herbs, whose efficacy far surpasses that of ginseng, and urine tests during competitions all come back negative (hormone-free). As for depression and anxiety disorders, they are even easier to treat. Simply by using the "Five Gods Decoction" to regulate one's 'essence', 'qi', and 'spirit', correcting the "coupling dysfunction" phenomenon between excitation and inhibition in the brain and restoring balance, depression and anxiety will naturally be cured. Dean Zhang promises: to restore vitality and vigor to patients with anxiety and depression is as easy as pie with the "Five Gods Decoction".
