When I was a child and teen even young adult ALL watermelon had big black seeds. As for Apricots and the B17 (Leatril) it is the bitter that kills cancer, they have bread out the bitter in our diet and got us hooked on sweets to feed the bad. I have gotten apricots that the seed was NOT bitter, so be aware they are not all the same or the bitter has been bread out of some. Dandelion, etc, think digestive bitters, look at the label and there you have a list of things that are good for digesting and curative of many things.
