Aluminum sulfate is indeed a substance with both medical and non-medical applications. Here's a breakdown of its medical uses:

• Minor cuts and abrasions: It acts as a coagulant, helping to stop minor bleeding by constricting blood vessels and promoting clot formation. It may be applied topically as a styptic pencil or solution.
• Antiperspirant: Aluminum sulfate is a common ingredient in deodorants and antiperspirants. It works by constricting sweat glands, reducing sweat production.
• Astringent: Aluminum sulfate has astringent properties, meaning it causes tissues to contract and dry out secretions. This can be helpful for treating minor skin irritations or excessive discharge from mucous membranes.

Important things to know:

• Aluminum sulfate is generally recognized as safe (GRAS) by the FDA for its intended uses.
• It's important to follow application instructions carefully, as overuse can cause skin irritation.

Here are some additional points to consider:

• There's ongoing research about the potential link between aluminum exposure and certain health conditions, but the evidence is inconclusive.
• If you have any concerns about using aluminum sulfate-based products, consult a doctor or dermatologist.

Beyond medicine: Aluminum sulfate has various industrial applications, including water purification and as a mordant in dyeing textiles.
