Hi becky, Yes, i didnt know either, but how abt those who claimed these did have the vit B17 that healed them. We neither have apricots, but i got curious abt this when there was in the local news a man who enjoyed his santol too much and swallowed too much also-(. You see santol seed could be as big/long as 1 inch and is quite big. And yes, some seeds are really edible, although we each do not know all that people from other places/continents are up to with their seeds. For ex., we always threw away papaya seeds.. then i learned from a woman's health forum abt these being ground just like pepper! While i tried that only once, i learned that it is indeed edible (food) for other people.
