Kamagra Oral Jelly is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, which is the same active ingredient found in Viagra. However, Kamagra Oral Jelly comes in a gel form rather than a pill, making it easier for some people to consume. It works by increasing blood flow to the penis when a man is sexually aroused, helping him to achieve and maintain an erection.
