According to Stelara, "Plaque psoriasis is a chronic (long-lasting) inflammatory skin condition that is caused partly by an overactive immune system. This causes the body to grow skin cells up to 10 times faster than normal. Instead of shedding, these skin cells pile up on top of each other and form red, raised patches of skin, called plaques."
This is what the National Psoriasis Foundation has to say about psoriasis:
There are five types of psoriasis. The most common form, plaque psoriasis, appears as raised, red patches covered with a silvery white buildup of dead skin cells. Psoriasis can occur on any part of the body and is associated with other serious health conditions, such as diabetes, heart disease and depression. Psoriasis is the most common autoimmune disease in the U.S. As many as 7.5 million Americans have psoriasis.
The most irritating symptom of psoriasis is the intense itching associated with the buildup of dry/dead skin cells. The most embarrassing symptom is the red, often raised, plaques of psoriasis that may cover large areas of the body. There are several natural ways to treat psoriasis for immediate relief of intense itching and the appearance of the plaque.
Applying an equal mixture of witch hazel and aloe vera gel to a sterile cotton pad and wiping the areas of plaque will bring fast relief of the itching and red appearance of the skin. Note that natural remedies should not be used while using prescription medicines for psoriasis. There could be an adverse interaction. If prescribed medicines are not very effective for you, discuss natural treatments with a physician before proceeding.
Use the spice turmeric on as many dishes of food as naturally appeals to you. This spice has excellent anti-inflammatory abilities.
Tea tree oil and apple cider vinegar give many people relief from an itching scalp. The tea tree oil should be mixed with a carrier oil such as extra-virgin olive oil to prevent the scalp from blistering. A ratio of one part tea tree to three parts olive oil should be used.
Don't use harsh soaps usually purchased from the grocery or discount stores. They contain a property that strips the first layer of skin, leaving it vulnerable to more irritation and itching. Use handmade soaps made from milk and oatmeal or plain glycerin.
Witch hazel and aloe vera can be applied up to six times a day. Tea tree oil can also be mixed with witch hazel to apply to the body or the scalp. Experience relief from the constant, irritating symptoms of psoriasis naturally.
If you don't already have a witch hazel shrub in your own yard, consider planting two or three for a reliable source of witch hazel. Otherwise, find it anywhere rubbing alcohol is sold.
