melatonin在jetlag上的作用是被医学界证实了的。 当然它并不是对每个人都有效，但值得试试。
Melatonin is the endogenous hormone that regulates circadian rhythm. It is made by the pineal
gland from tryptophan. It is commonly used to treat jet lag and insomnia. It is claimed to reduce the
number of days required to establish a normal sleep pattern when travelling, and can also decrease the
time it takes to fall asleep (sleep latency).
The Cochrane review demonstrated that 9 out of 10 RCTs (randomized controlled trials) did show that it was effective for use in
treating jet lag. No conclusive or results have been obtained in studies investigating its use for insomnia
however. Generally, there is sufficient evidence for its efficacy in jet lag, but not as a sleeping aid.

楼主说的药自称是homeopathic medicine, 也就是把任何有效物质稀释上万亿倍（就是水），然后卖给你。 当然自称是有效的。参照WebMD对它还作用介绍：
Homeopathy is based on the idea that "like cures like." That is, if a substance causes a symptom in a healthy person, giving the person a very small amount of the same substance may cure the illness. In theory, a homeopathic dose enhances the body's normal healing and self-regulatory processes.
A homeopathic health practitioner (homeopath) uses pills or liquid mixtures (solutions) containing only a little of an active ingredient (usually a plant or mineral) for treatment of disease. These are known as highly diluted or "potentiated" substances. There is some evidence to show that homeopathic medicines may have helpful effects.
关于no-jet-lag这个药，我看了一下它自己网站对于它效果的介绍，http://www.nojetlag.com/jetlag6.html， 只能说这个study很差. 虽然它自称是是randomized double bind trial, 里面很多trial design重要的部分被忽略过。几乎没有任何journal会publish.
