People have used herbs to treat skin conditions for centuries, and recent research has supported the idea that some herbal treatments may improve psoriasis symptoms.
Psoriasis is an inflammatory condition that causes red, scaly patches of skin to develop, often on the elbows, knees, or scalp.
There is no cure for psoriasis, though treatments and natural remedies can help people to manage their symptoms. Many herbs have the potential to reduce inflammation or slow down skin cell growth, which can help with psoriasis symptoms.
This article will discuss the herbal remedies that currently have the most robust evidence base as treatments for psoriasis.
Mahonia aquifolium is a flowering plant that comes from the mahonia shrub. It is also known as Oregon grape. This herb has a history of use in treating inflammatory conditions, including psoriasis.
Mahonia aquifolium contains berberine, which may help to suppress some of the inflammation that psoriasis causes.

There is some evidence that vitamin D creams can help with psoriasis.
A 2013 systematic review found evidence to suggest that using vitamin D creams could be as effective as corticosteroid treatments for treating symptoms. However, corticosteroids were more effective for psoriasis on the scalp.
Using herbal remedies on the skin can cause side effects in some people, such as:
- skin irritation
When using essential oil, always dilute it with a carrier oil beforehand. People can apply creams containing herbs directly to the skin if the manufacturer recommends this method.

The effectiveness of treatment will depend on many factors, such as the severity of the condition or the time of diagnosis.
