I searched for info on Watermelon seed tea. Not much here... too bad. It is powerful stuff.

I have kidney gravel and have had problems getting over kidney infections since bacteria GETS STUCK IN THE GRAVEL!!
I finally used Watermelon Seed Tea and could see debris coming out after the first cup.

I made the first cup strong - half the water - by mistake but seeing the junk coming out convinced me.

Unfortunately it takes a long time to get seeds out of the melon and what a mess. Oh well. Do it on a picnic table outside!!! Plus of course as you all know... they have bred out the big seeds so ya only get 4 tablespoons from one melon. What a pain. But do this in the summer and then start again next summer when the melons are in. It works.
