Frankincense, the precious fragrance that was among the gifts that the wise men from the East brought to the infant Jesus, is now being studied intensely for its cancer-fighting properties. There's something in frankincense that compels cancerous cells to "reject" nuclei and reset back to what the normal governing gene sequence should be.
It's a very educational and intriguing read, especially if you've ever read the Christmas story out of the Bible and wondered what the heck frankincense is supposed to be :-)
(And although that painting has nothing to do with frankincense specifically, I'll give props to whoever can tell me the name of it, who painted it and what its historical significance is ;-)
