Summarize this article in one sentence.
Apple cider vinegar contains its own healing, anti-inflammatory, and anti-fungal properties. It is also known to treat burns and skin inflammations. You can soak the affected body part in a mixture of equal parts apple cider vinegar and water.  You can also use cotton balls to apply ACV to the skin. Just pour small amounts of apple cider vinegar to the cotton balls and directly apply to affected areas. You can do this twice per day until patches and redness have improved. If your skin gets easily irritated refrain from using this method, as apple cider vinegar is quite acidic. If you have an aloe vera plant at home you can just slice one of its leaves horizontally and apply the gel-like sap directly onto the plaque. This will smooth and naturally moisturize dry scaly patches.  You can also purchase aloe gel in local pharmacies and grocery stores. Apply 3 times a day or more, depending on the dryness of the patches. Sunlight exposure is the simplest yet one of the most effective methods of treating plaque psoriasis. Try exposing affected body parts to sunlight for 10 minutes of noontime sun every day and gradually increase the exposure time by 30 seconds each day.  Take precautions as heat from sunlight causes sunburns. If you choose to expose yourself to sunlight don’t apply any cream as this can make you more sensitive to heat but you should apply sunscreens to unaffected areas. If you expose the affected skin to sunlight on a consistent daily basis, you will gradually notice your symptoms improving over time. Coal tar is an effective treatment for plaque psoriasis. It is made of coal and wood and helps to reduce inflammation, remove scales, and slow the growth of excess skin cells.  Coal tar penetrates layers of the skin and reduces excessive thickening and scaling of the skin – it does this by breaking down a protein named keratin, which is responsible for skin growth and formation. This is also an OTC drug/ointment/cream that can be bought in most pharmacies. The greater the concentration of this product, the more it is effective. Tar shampoo can be particularly good for treating plaque on the scalp.
Soak the affected area in apple cider vinegar. Apply aloe vera to the plaque. Expose the affected area to plenty of sunlight. Purchase coal tar from a natural remedies store or pharmacist.
