Go the the search box at the top of this page and run a search for Watermelon seed tea. It helps to put the words in quotation marks to avoid miscellaneous links to each word.
I love the search function on this website! I have picked up more information than I anticipated when looking up stuff using this search.
You'll find directions for making the tea yourself instead of having to spend time and money looking for it and purchasing a prepackaged tea.
