Health Benefits of Alum

From ancient Ayurveda to modern skin remedies, Alum—a humble white crystal—has earned a spot in the Indian wellness cabinet. Known for its antibacterial, anti-inflammatory, and antiseptic properties, alum has been used for centuries in everything from healing wounds to purifying water. 

And just like alum quietly prevents infections and skin problems, a good health insurance plan shields you from unexpected medical expenses—from OPD consultations to hospitalizations. Compare health plans starting Rs. 9.3/day and secure smarter wellness. 

Let’s explore the types of alum, its many health benefits, everyday uses, and the precautions you should take while using it. 

What is Alum? 

Alum, or Potassium Aluminum Sulfate, is a crystalline compound with natural antiseptic, astringent, and deodorizing properties. In India, it’s widely known as “Phitkari” and often used in traditional home remedies to treat acne, bleeding gums, and body odor, or even as an aftershave. 

Alum is commonly found in the form of a solid block (alum stone), powder, or crystal, and works by tightening tissues, disinfecting surfaces, and reducing inflammation. It’s also used in the food industry, water purification, and textile dyeing. 

There are several types of alum used for various medicinal, industrial, and household purposes. The most common types include: 

• Potassium Alum (Phitkari) – The most commonly used form in Indian homes for skin care, water purification, and shaving cuts. 
• Ammonium Alum – Used in water purification and cosmetic industries. 
• Sodium Alum – Found in baking powder and food preservation. 
• Chrome Alum – Used primarily in tanning leather and dyeing fabrics. 
• Aluminum Sulfate – A common coagulant in municipal water treatment. 

Note: Potassium alum is the only type suitable for skin and health-related home remedies. 

Here are the most popular and trusted uses of alum and how it helps your health and hygiene: 

1. Treats minor cuts and shaving nicks 

Alum’s astringent properties help seal small wounds, stop bleeding, and prevent infection. It’s often used as an aftershave in barbershops across India. 

 2. Heals mouth ulcers and bleeding gums 

A pinch of alum powder mixed in warm water makes an effective mouth rinse for ulcers, gingivitis, or bleeding gums. It disinfects and tightens gum tissues. 

 3. Fights acne and pimples 

Alum stone can be rubbed gently on acne-prone skin to reduce inflammation and bacterial activity. It helps dry out pimples and prevent new breakouts. 

 4. Natural deodorant 

Thanks to its antimicrobial effect, alum blocks odor-causing bacteria in the underarms and feet. It’s a natural, chemical-free alternative to commercial deodorants. 

 5. Skin tightening and anti-ageing 

Alum’s astringent action helps tighten pores and may reduce early signs of skin sagging and wrinkles with regular use. 

 6. Purifies drinking water 

Alum works as a coagulant that settles suspended particles in muddy or contaminated water—making it clearer and safer to consume. 

While natural remedies like alum offer first-aid support, health insurance ensures full protection for deeper health issues—from dental infections to skin conditions needing a dermatologist. Check coverage & benefits now.

Despite its natural properties, alum must be used cautiously. Overuse or improper application can lead to: 

1. Skin Dryness or Irritation 

Frequent or undiluted use of alum can strip the skin’s natural oils, causing dryness, redness, or flaking. 

2. Burning Sensation 

When applied to open wounds or sensitive areas, alum may cause a sharp stinging or burning sensation. 

3. Allergic Reactions 

Though rare, some people may develop rashes or itching due to alum sensitivity—especially on delicate facial skin. 

4. Oral Overuse Risks 

Using excess alum for mouth rinsing or swallowing it accidentally can lead to mucosal damage or even gastrointestinal irritation. 

5. Kidney Load (in very high doses) 

If alum is ingested in large, continuous quantities (like in some old-school water treatments), it may burden kidney function over time. 

Pro Tip: Always use cosmetic-grade alum for skincare and follow dilution instructions for oral or topical use. 

Conclusion 

Alum stone may be old-school, but its medicinal uses are backed by both tradition and science. Whether you use it to treat acne, purify water, or stop a shaving cut, alum offers simple, effective solutions with very few side effects when used correctly. 

That said, it’s not a replacement for modern medical care—and shouldn’t be used to treat serious infections or internal conditions. 

From skin allergies to oral infections, even minor issues can snowball into expensive treatments if ignored. Choose Bajaj Finserv Health Insurance to stay covered for consultations, tests, OPD, and more—with plans starting at Rs. 9.3/day*.
