  • Acne & Boils: Local infection, hormonal imbalance or internal toxicity causing inflammation. Both conditions should be treated internally and externally. Acne generally occurs during teenage years. Boils, however, are the body’s way of removing toxins, and may signal a weakened immune system, diabetes, or deep-seeded bacterial infection.

Research: A recent study had shown Calendula’s ability to prevent dermatitis in breast cancer patients during radiation.

The German health authority recognized and proved Calendula’s wound and anti-inflammatory healing ability. Plant effectively seals the wound with new tissue while reducing an inflammation of the wound. The key drivers in healing process seems to be triterpenoid compounds such as oleanolic acid, which has the ability to inhibit a variety of bacteria. The speedy recovery, and reduction in inflammation, can be also attributed a triterpenoid compounds which act as an antioxidant, reducing the skin’s exposure to oxygen radicals.

Another study was done by randomly selecting 254 breast cancer patients about to undergo radiation treatment. They were offered to apply 2x/day either one - a common medicine known as trolamine, or a Calendula ointment. The results shown that patients who chose Calendula ointment during their treatment experienced lower dermatitis and had fewer interruptions in their treatment time.

Another study has shown that Calendula helps to increase blood flow and oxygen to the affected area, which helps with new tissue generation. It has also been proven that the plant acts as a natural moisturizer by hydrating skin and improving skin’s firmness.
