However, a variety of topical and systemic antipsoriatic treatments have been triad but none is without side effects. Coal tar has been used as a standalone treatment for psoriasis or in combination with other therapies. Aloe vera is one of the most popular medical plants. It has anti inflammatory and immune modulatory functions.

The results revealed that the mixture was well tolerated safe and effective, which suggests its possible use as an alternative treatment for psoriasis vulgaris.
