Chamomile tea is useful for many different illnesses due to its anti-inflammatory and immune-boosting properties. This also makes it an effective tool in the battle against festering, which often occurs when an open wound becomes infected. Chamomile tea can be consumed to boost the immune system and prevent the infection, or the chamomile leaves can be ground up into a paste and applied directly to the wound. This will dry the wound, reduce the swelling and inflammation, speed the healing process, and prevent any bacteria or viruses from causing festering.
