Ephedrine is phenethylamine, an active compound available in a plant species Ephedra sinica. It is poisonous, so its consumption results in harm to the human body. It contributes to weight loss. Overtime use is very dangerous because its side effect is life-threatening. Ephedrine is a fine white, crystalline substance that is soluble in water. Because of this, it is easily consumed.
It is banned by many sports organizations because it increases norepinephrine levels, which affects general physical response, while Ephedra is the medical preparation of plants from their species Ephedra sinica, typically for consumption. It consists of the active compound ephedrine, alongside pseudoephedrine, and some other stimulants, including caffeine. It is very dangerous to human health due to that; it is banned in the United States. Ephedra is used for the same purpose as ephedrine because it contains ephedrine, but it is said to be more effective because it is combined with other stimulants.
