Williams et al15 reported two RCTs in one publication. In the
first study they randomized 194 women receiving radiation therapy
to be treated with aloe vera gel, self-administered to the radiation-exposed
skin twice per day or with placebo gel. The severity
of the dermatitis was judged weekly during the 10 weeks treatment
period both by the patients and by their healthcare
providers. There was no difference between the treatment group
and the placebo group.
