Magnesium sulphate paste is a medication found in pharmacies used as a drawing agent. Magnesium sulphate originally came into medical use as early as 1618 when a cow herder Henry Wicker discovered magnesium sulphate and its use as a laxative. This was used for 350 years. Nowadays, it is used in Epsom bath salts and as a dehydrated paste used as a drawing agent.
To begin with, ensure the area applied to is clean and there is no broken skin. Start by stirring the paste till an even mixture is produced. Thereafter, apply the paste liberally to the affected area and cover it with a clean dressing. This can be done twice a day till the paste draws out the object. Ensure to keep an eye out for signs of an infection.
Magnesium Sulphate Paste is not just magnesium sulphate, it also contains glycerol which works by retaining moisture. The Magnesium sulphate is dried so does not contain any water and when applied to the skin it works to draw out moisture from an inflamed area of skin.
Do not use if you are allergic to any of the ingredients in the paste. Also do not use of any broken skin or any areas that may be infected. Like any medication, side effects are possible. Given it is a topical paste, skin reactions are possible. If you have any side effects, stop applying the paste and talk to your doctor or pharmacist.
