I posted this in Hawaii section, but I'm hoping someone here have it:

"Anyone here know where to find the medicinal plant Blumea balsamifera. It is called "sambong" in the Phillipines and it used as tea to prevents ailments such as kidney stones.

Please, if anyone know where to get cuttings/seedlings or a fully grown plant in Oahu it will be much appreciated. I'm going to check my local flea market this weekend to see and ask a vendor, who especialize in Filipino plants, if he has one, but until then please keep a look out for the said plant."

Does sambong set seeds, and how long is the seeds viable?
