Article in English: Gel from the aloe vera plant is a traditional treatment for wounds, burns, infections, and some kinds of joint pain and arthritis. You can use it directly on the joints or drink aloe vera juice to decrease inflammation. Aloe vera may be useful for RA because of its anti-inflammatory properties, its property as a pain-reliever (likely due to the anti-inflammatory properties), and in speeding up wound healing. It is also a safe moisturizing and anti-aging agent.  The gel comes from the central part of the aloe leaf, known as the "inner fillet." It contains larger complex sugars than aloe juice does. These complex sugars are thought to be responsible for the benefits of aloe.  The juice is extracted from the outer leaves and also contains complex sugars. If you have a mature aloe plant, cut off a leaf using a pair of sharp scissors and peel away the outer leaf to reveal the clear gel inside. Use your fingers to get the gel out or cut the end off the leaf and squeeze the gel out. If you want to purchase the gel, check online or at your local health food store. Buy organic aloe vera with no additives or preservatives. At first, apply the aloe to a small area to test for any possible reactions. If a rash or other problems develop, stop using it. If there's no skin irritation, spread the gel onto the areas that are bothering you the most. Apply it like you would any other lotion. This will give you temporary relief from the pain of rheumatoid arthritis. As long as there's no skin irritation, you can keep treating the pain with aloe vera as long as you want. Most people don't experience side effects, but aloe may cause redness, a burning or a stinging sensation and rarely, a short-term rash. Aloe vera juice has been reported to decrease immune responses, which may be helpful in RA. Drinking aloe vera juice can cause cramping, diarrhea and gas. If this happens, stop drinking it. Drinking aloe vera juice can lower blood sugar and interfere with diabetes medications, so don't drink the juice for more than 3 to 4 weeks....
