Bitter gourd does not contain toxic substances, so it is certainly possible to eat it raw, and the nutritional value of eating it raw will be higher than that of eating it after cooking, but it needs to be cleaned before eating it raw.

However, bitter gourd contains more oxalic acid and bittersweet. If it is eaten raw, it tastes bitter, which is not acceptable to everyone. Therefore, for the general population, it is recommended to blanch it before cooking it, so that the taste will be better.
