Camel hump and colocynth oil, very very excellent for knee pain, stiffness, roughness, and difficulty climbing stairs. I make it without any preservatives or additives, God is my witness. Its use is easy and the results are satisfactory, God willing, and by God, I did not sell it until I tried it on myself and it benefited me. The location is Mahayil, and we ship refrigerated outside Mahayil.
