What Is Allantoin?

Allantoin is a chemical ingredient and diureide of glyoxylic acid, often used to treat dry, rough, and itchy skin due to its moisturizing, skin smoothing, and wound healing properties (1),(2).

Allantoin also occurs naturally. Comfrey, a shrub that grows in some parts of Asia, North America, and Europe, is a reservoir of allantoin. The roots of comfrey contain allantoin and are often used to prepare ointments, creams, and lotions (3).

However, the comfrey plant contains toxins, which may cause serious side effects if used in its natural form. Luckily, its extracts are refined and processed in the labs to remove all toxins to make them suitable for cosmetic and skin care products (4).

Allantoin is also found in sugar beets, chamomile, wheat sprouts, and in certain types of bacteria and animals but not as abundantly as in comfrey.
