Apple seeds are small, brown seeds found within the core of an apple. They are typically less than 1 centimeter in length and have a hard, slightly glossy outer shell. Apple seeds contain a small amount of amygdalin, a substance that can release cyanide when it comes into contact with digestive enzymes in the body. However, the amount of cyanide in apple seeds is typically not enough to cause harm unless consumed in very large quantities.

Despite their potential toxicity, apple seeds have been used in traditional medicine for centuries due to their rich nutritional content. They are a good source of protein, healthy fats, and fiber, as well as a variety of essential vitamins and minerals including vitamin C, vitamin K, potassium, and iron.

Apple seeds are not typically consumed on their own due to their potential toxicity, but they can be used to make apple seed oil, which is sometimes used in cooking and as a skin care ingredient. However, it is important to note that consuming large amounts of apple seeds or apple seed oil can be dangerous and should be avoided.
