The current interest in melatonin is wintnessed by the growing number of scientific papers directly or indirectly dealing with this molecule, in the last 10 years, the mean number of articles has doubled and reports on new compounds acting at the melatonin receptors abound, although the search for a clear therapeaatic role for these ligands is still under way beside the scientific interest, there is a contemporary, but largely independent, explosion of a free market of various products containing mt, which have been presented at antiage agents protecting against differe kinds of injuries, although this action still lacks a solid scientific foundation. indeed while a number of physiological action of mt are coming to light, the exact role and the the real therapeutic benefit of this compound still remain unclear, both have been the subject of debate. with a lot of potential actions still to be fully demonstrated and with some mechanisms deserving more clarification, in sense, the appellation of the hormone of darkness, attributed to mt beacause of its characteristic concentration / time profile, seems extremely appropriate
除科學興趣以外，也有暫時的，在很大程度上不可靠的有關各種含有mt的產品開發的探索，如出現的保護多種損傷的抗衰老劑。盡管這些產品的作用仍缺少堅實的科學基礎，事實上當mt的許多生理作用研究清楚后，這種物質的確切作用和真實的治療效果仍不得而知。有許多潛在的作用需要充分論證，有些機理需要進一步區分，在某種意義上說，稱mt為黑暗激素，主要是由於在某一時間的特定濃度分佈似乎更合適。 -
