Preparation H Cooling Clear Gel helps to shrink the tissues swollen by inflammation, and can act like a lubricant for easing painful bowel movements when the skin is dry and sore. Preparation H Clear Gel is a unique combination of natural witch hazel extract and soothing moisturising ingredients in a clear gel base. It is effective against the pain, irritation and itching of piles. The non-greasy gel format is easy to apply and is suitable for use during pregnancy and breast feeding.
