Calendula

Did some research on skin rashes worst enemy.
One of the best I came across is this: Calendula (The mad skin plant)

Calendula is truly the miracle worker of the skin, whether a person has lumps or bumps, scabs that won’t heal, eczema, athlete’s foot, acne, or even herpes sores. Calendula has been used to treat every skin condition ever dreamed up. It is an all-purpose skin-healing agent. Not surprisingly, wherever calendula grows, it is used to treat the skin.

Not only is calendula a product with a universal endorsement, it has stood the test of time. We are talking about a track record of at least 1,000 years. Even more exciting, it is perfectly safe.
