There are two forms of the plant, one (often with white flowers) producing sweet almonds, and the other (often with pink flowers) producing bitter almonds. The kernel of the former contains a fixed oil and emulsion. Bitter almond (Pak Hung) should not be confused with "sweet almond." Sweet almond seeds do not contain amygdalin and can be eaten, whereas bitter almonds can be toxic. The poisonous hydrocyanic acid contained in bitter almonds breaks down when heated, so the poison is unlikely to accumulate when used in any cooked dish. It is unwise to eat raw bitter almonds. Serious almond poisoning is rare in adults, but children may die after eating just a few bitter almonds.
