feverfew

I love these guys! I do chew a leaf for headache relief & it works well for me, although I did read a caution that overuse could lead to mouth cancer, herbal remedies being just as likely to have downsides as our usual ones.

yes...that's the prime directive, (for those of Startrek generations)...or the first tenet of Hypocrates..."do no harm" and for every "good" there is always a "caution". Even our "usual" medications and treatments have their origins in the herb garden.
I had an aged auntie who claimed that comfrey could cure anything...even cancer. Imagine .... from what I can understand of the science...comfrey can be carcinogenic...it's main benefit when taken being a vitamin source. perhaps just another green vegetable!? lol. guess the best advice is from another Greek.... "all things...in moderation"
I suppose most herbalists are self medicators...present day medicine frowns on that. If I have a choice...I prefer the most "natural" or the cure closest to the natural source. Im sure we all would, right? perhaps you could boil willow bark next time you have a headache, because in low doses it's even good for your heart!...
Wellll.... : - )) !!
