What you're describing is a little puzzling, since adrenaline usually eases pain, it doesn't make it worse or provoke it. Adrenaline is designed to help you cope better with stress and danger, so what it does is actually make you feel better, more powerful, speedier, more alert, and decreases your ability to feel pain.
How Long Does It Take Aloe Vera to Grow? Aloe vera plant grows within 2 to 3 weeks of initial planting, enough that you begin to see the growth. In the early stages of aloe vera plant growth, use your watering can to keep the soil moist, but be sure to be moderate.
Cut off one of the outermost leaves of your aloe vera plant using a sharp knife. Choose a leaf that is thick and green and cut it at a slight angle, relatively close to the base of the plant. Stand the aloe leaf cut-end down in a cup for about 15 minutes. This lets the latex (sap) drip out of the plant. The latex of the aloe vera plant is a laxative and needs to be removed before storage. There may be no latex dripping out if the leaf is small.
