Two University of Colorado (USA) Cancer Center studies, the second of which was published on Jan 28th 2013, have demonstrated that silibinin – the main active ingredient in milk thistle seed extract
– has efficacy against both ultraviolet A (UVA) and ultraviolet B (UVB)-induced skin carcinogenesis and photo-aging.
Milk thistle is also widely regarded as having remarkable liver
protection / healing qualities (this is what it is currently most often
employed for) and has also shown some promising results in lab research
against breast and prostate cancer cells. 
Did you know that it has also
been employed as an antidote in some types of poisoning and is even
claimed by some to be a hangover cure?
