For generations, alum (commonly known as fitkari in many households) has been a staple ingredient. Most of us recognize it as that translucent white stone used to purify murky water or as an aftershave block by men. But did you know that this humble, inexpensive crystal is a powerhouse of benefits?

Beyond its well-known ability to clarify water, alum possesses antiseptic, astringent, and hemostatic properties that make it incredibly useful for various home remedies and personal care routines. Let’s explore 5 amazing benefits of alum that might just surprise you.

1. A Potent Natural Aftershave and Antiseptic

This is perhaps its most classic use. The reason barbers have used an alum block for centuries is its incredible ability to soothe the skin and stop bleeding from minor nicks and cuts.

• How it works: Alum is a hemostatic agent, meaning it constricts blood vessels to stop bleeding quickly. Its antiseptic properties also help prevent infection in small razor burns or cuts.

• How to use: After shaving, simply wet the alum block with cold water and gently rub it over your shaved skin. You will feel a slight tingling sensation, which is normal. Rinse your face after a minute or two and apply a moisturizer.

2. Effective Remedy for Canker Sores (Mouth Ulcers)

Mouth ulcers can be incredibly painful and annoying. Alum powder is a well-known traditional remedy to speed up their healing process.

• How it works: Its strong astringent property helps to dry out the sore and reduce inflammation, providing quick relief from pain.

• How to use: Take a tiny pinch of fine alum powder and place it directly onto the canker sore. It will sting for a minute—be prepared! Let it sit for about 30-60 seconds, then rinse your mouth thoroughly with water. Do not swallow it. You can repeat this once or twice a day for 2-3 days.

• Important Note: Do not overuse it, as excessive use can irritate the mouth lining.

3. Natural Deodorant and Cure for Smelly Feet

Struggling with body odor or smelly feet? Alum can be a fantastic, chemical-free alternative to commercial deodorants.

• How it works: Body odor is caused by bacteria breaking down sweat. Alum is bacteriostatic, meaning it inhibits the growth of bacteria. By controlling bacterial growth, it effectively prevents the odor.

• How to use:

  • For underarms: Wet an alum block and rub it gently on clean underarms after a shower. Alternatively, dissolve a small amount of alum powder in water and apply it with a cotton pad.

  • For feet: Add a tablespoon of alum powder to a basin of warm water and soak your feet for 15-20 minutes. This not only combats odor but also helps soothe tired feet and heal minor cracks.

4. Skin Tightening and Treating Acne

Due to its astringent nature, alum is often used in DIY face packs to tighten skin and treat acne.

• How it works: It helps cause tissues to contract or shrink, which gives a temporary tightening effect to the skin. For acne, its antiseptic properties help kill acne-causing bacteria and dry out pimples.

• How to use:

  • For tightening: Mix a pinch of alum powder with rose water or Multani mitti (Fuller’s earth) to make a paste. Apply it to your face, let it dry for 10-15 minutes, and rinse with cool water. Use this once a week.

  • For acne: Apply a paste of alum powder and water directly onto the pimple. Leave it on for 10-15 minutes and wash it off. Note: Always do a patch test first, especially if you have sensitive skin, as it can be drying.

5. Prevents Premature Greying of Hair & Treats Lice

In traditional practices, alum has found its place in hair care as well.

• How it works: It is believed that alum, when used with rose water, can help maintain the natural black color of hair over time. Its strong nature is also effective in killing head lice.

• How to use:

  • For lice: Mix alum powder with a little water and apply this paste to the scalp. Leave it for some time and then wash your hair.

  • For hair color: A paste made from alum powder and rose water can be applied to the scalp once in a while to potentially prevent premature greying. Always consult a professional before using strong treatments on your hair and scalp.

A Word of Caution

While alum is incredibly useful, it should be used with care:

• External Use Only: Most home remedies involve external application. Ingesting large amounts of alum can be toxic.

• Patch Test: Always perform a patch test on a small area of your skin before using it on your face or sensitive areas.

• Moderation is Key: Overuse can lead to excessive dryness or irritation of the skin and mucous membranes.

So, the next time you see that white block of crystal, remember it’s a versatile household hero waiting to be used!
