In recent years, natural and sustainable approaches to health have gained popularity. One trend that often circulates online is the idea that boiling eggshells can prevent or treat disease. But how much of this is supported by science? Let’s break it down.

What Happens When You Boil Eggshells

Eggshells are made mostly of calcium carbonate (about 95%), along with small amounts of protein and trace minerals such as magnesium and phosphorus. Boiling them produces a few important effects:

• Kills bacteria: Boiling destroys pathogens like Salmonella, making the shells safe to handle.

• Releases some calcium into the water: This is why “eggshell tea” or eggshell water is sometimes used as a supplement or for plants.

Boiling makes eggshells cleaner and safer to use, but it does not transform them into a medicine.

Can Boiled Eggshells Cure or Prevent Disease?

The short answer: no.

Boiled eggshells do not create substances that can directly fight infections, viruses, or chronic diseases in the human body. However, they can contribute to overall health in indirect ways.

1. A Natural Source of Calcium

Calcium is essential for:

• Strong bones and teeth

• Proper nerve signaling

• Muscle contraction and function

A deficiency can lead to osteoporosis, brittle nails, or muscle cramps. By boiling, drying, and grinding eggshells into a fine powder, you can create a natural calcium supplement.

Important: Make sure the eggshells are thoroughly sterilized and ground into a fine powder to prevent contamination or digestive discomfort. Always consult a doctor before using homemade supplements.

2. Reducing Waste and Supporting Sustainability

Using eggshells instead of discarding them contributes to eco-friendly living. While this doesn’t directly cure disease, reducing waste and living sustainably can have a positive impact on your environment and well-being.

3. Healthier Plants, Healthier Food

Eggshell water is often used as a natural fertilizer:

• Calcium strengthens plant cell walls

• Supports plants in resisting rot, pests, and fungal infections

• Produces more nutritious crops

Healthier plants lead to more nutrient-rich food, which indirectly supports human health.

Common Myths About Boiled Eggshells

Some misconceptions include:

• “Drinking eggshell water can cure arthritis or diabetes.”

• “Boiled eggshells detoxify the body.”

• “Eggshells can replace medicine.”

These claims are not supported by scientific evidence. While eggshells are a source of calcium and minerals, they are not a substitute for medical treatment or a balanced diet.

Safe Ways to Use Boiled Eggshells

For a calcium supplement:

1. Rinse eggshells thoroughly.

2. Boil for 10 minutes to sterilize.

3. Dry completely (sunlight or oven).

4. Grind into a fine powder using a blender.

5. Store in a clean container and use small amounts (½ teaspoon per day) in smoothies or soups.

For plants:

1. Boil crushed eggshells in water for 10–15 minutes.

2. Let cool and strain.

3. Use to water plants, providing calcium and balancing soil acidity.

Conclusion: Boiling eggshells is a safe way to create a natural calcium source and support sustainable practices, but it does not cure disease. Use eggshells responsibly, and rely on proper nutrition and medical care for maintaining health.
