Vitamin C
Vitamin C, also known as ascorbic acid and -ascorbic acid, is a vitamin found in various foods and sold as a dietary supplement. It is used to prevent and treat scurvy. Vitamin C is an essential nutrient involved in the repair of tissue and the enzymatic production of certain neurotransmitters. It is required for the functioning of several enzymes and is important for immune system function. It also functions as an antioxidant. 
Current evidence does not support its use for the prevention of the common cold. There is
the plant. For this kind of problem, pesticides and sprays do not always work as the shell of the insect protects it. If this becomes a severe problem, you will have to get rid of the plant. Also if this happens, make sure it is moved away from any other surrounding plants because the bugs could infect them as well. Other than that, this plant is very easy to take care of and thus, it is good for beginners. Propagation of "Nephthytis" is fairly easy as well.
