Purslane is marvelous for oral cancers or precancers!!!!! As good as the hideous steroid mouth swish liquid!! Yes, you can make a tincture or whatever out of it, but I just eat it right out of my friend’s yard. Season hasn’t started yet in SoCal. I am bringing some to my oral oncologist to show him, he is top of his field and interested. There are a few scientific studies. (Below link) And it tastes way better than dandelions (which I can’t eat unless I boil them, so bitter).

I have come to respect weeds after my friend started foraging and making teas and tinctures. Marijuana is a weed; I’ve seen it growing like one in Kathmandu. And it helps a lot of things too though I do not wish to get high.
Yaelle, they make cannabis now that has no psychoactive properties.
It has all the other good stuff, though: palliatives, anti-inflammatories, etc.
