Not sure of this one medically @shann but maybe a story worth relaying.Some years ago I attended a party and met a much older retired farmer from the Mallee here in SA. He had had a serious tractor accident which had left him with an open wound on his leg which would not heal and he was told by his medical staff they could do nothing further. He spoke at length about how aloe Vera had healed him.He was not a salesman just a typical old bush farmer I think we call cocky farmers. What struck me was the conviction with which he spoke and he seemed a most unlikely zealot for alternative medicine.I have never tried it for wound healing but we use it extensively in summer for sunburn with great success. May be worth chatting to medical staff in the circumstances- @primek maybe you might have some thoughts about this.
