In the United Kingdom, a medication containing magnesium sulfate, called "drawing paste", is claimed to be useful for small boils or localised infections, [19] and removing splinters. [20] The standard British Pharmacopoeia composition is dried magnesium sulfate 47.76% (by mass), phenol 0.49%, and glycerol to balance. [19]
Magnesium sulphate paste is used as a drawing salve to treat small boils and infected wounds and to remove 'draw' small splinters. [2] Black ointment, or Ichthyol Salve, also called Drawing Salve, has been traditionally used to treat minor skin problems such as sebaceous cysts, boils, ingrown toenails and splinters.
Magnesium sulfate or magnesium sulphate is a chemical compound, a salt with the formula MgSO 4, consisting of magnesium cations Mg 2+ (20.19% by mass) and sulfate anions SO 2− 4. It is a white crystalline solid , soluble in water but not in ethanol .
In the European Union, the European Medicines Agency has jurisdiction and the relevant documents are called the "summary of product characteristics" (SPC or SmPC) and the document for end-users is called the "patient information leaflet" or "package leaflet". The SPC is not intended to give general advice about treatment of a condition but does ...
Magnesium is absorbed orally at about 30% bioavailability from any water soluble salt, such as magnesium chloride or magnesium citrate. The citrate is the least expensive soluble (high bioavailability) oral magnesium salt available in supplements, with 100 mg and 200 mg magnesium typically contained per capsule, tablet or 50 mg/mL in solution.

The structures of solid magnesium citrates have been characterized by X-ray crystallography.In the 1:1 salt, only one carboxylate of citrate is deprotonated. It has the formula Mg(H 2 C 6 H 5 O 7) 2 The other form of magnesium citrate has the formula Mg(HC 6 H 5 O 7)(H 2 O) 2, consisting of the citrate dianion (both carboxylic acids are deprotonated). [1]
But a saturated magnesium sulphate solution is not a diluted solution; it has a high content of salt. The value 25.5 g/100 ml is also close to 26 g per 100 cc for cold water (Weast R. C. (editor), CRC Handbook of Chemistry and Physics, 57 ed., CRC Press Inc. 1976-1977, page B-129) but the temperature is not 20 °C but 0°C.
