There are many natural remedies to try for PsA. Most of these do not have much scientific research supporting their use. The use of these remedies is backed mainly by anecdotal evidence.

Axar.az reports that natural remedies for psoriatic arthritis include the following:

1. Apple cider vinegar

Apple cider vinegar has a lot of buzz for, supposedly, being a miracle cure-all. For treating PsA, people may find it useful if applied to patches of psoriasis on the scalp. However, this should be avoided if the areas are cracked and bleeding.

2. Tea tree oil

This essential oil may ease skin inflammation caused by PsA. However, science is cautious to recommend this as a treatment because it may aggravate more sensitive skin.

3. Oats

Adding oats to a bath or using oats in a paste can help relieve itchy patches of psoriasis. While there's little scientific evidence supporting oats as a treatment for psoriasis, oats are highly regarded in folk medicine as one of nature's best skin soothers.

4. Turmeric

Turmeric is highly regarded for its anti-inflammatory properties. Studies have shown turmeric may be able to alter gene expression, easing PsA symptoms. People with PsA can either add the spice liberally to their food or take turmeric capsules.

5. Capsaicin

Capsaicin is what makes chili peppers hot and may be useful by blocking pain receptors. Some research has also found that when used in over-the-counter creams, capsaicin may reduce psoriasis symptoms as well.

6. Aloe vera

This soothing balm from an aloe plant may provide cooling comfort for irritated patches of psoriatic skin. However, aloe vera should only be used topically and never ingested. Taking it orally may be dangerous.

7. Epsom salts

A warm bath with Epsom salts may help reduce joint pain and inflammation. Epsom salts contain magnesium, a mineral that boosts bone health and may soothe itchy skin. Warm water also helps loosen joints and relieve pain. People with diabetes should be wary when using soaks of Epsom salts as they can stimulate the release of insulin.

8. Oregon grape

Some studies suggest that applying creams with Oregon grape (Mahonia aquifolium) can ease psoriasis skin irritation. Like aloe vera, Oregon grape should only be used topically.

9. Fish oil

Joint pain may be reduced by fish oil. Omega-3 fatty acids found in fish oil help block inflammation and ease painful swelling.

10. Ginger

A root of ginger is well-known in folk medicine for having many anti-inflammatory properties. Some studies have shown that taking ginger three times a day can reduce knee pain caused by osteoarthritis.
When trying these natural remedies, people with PsA should remember that these remedies are not a substitute for prescribed treatments.
