THE MAGIC OF BOILED EGGSHELLS
INTRODUCTION
Eggshells are one of nature’s richest sources of calcium carbonate (about 95%), along with magnesium, phosphorus, and trace minerals. Many traditional cultures used eggshells by boiling and grinding them into a fine powder.Boiling kills bacteria, while grinding turns them into a safe mineral booster that can be used for:
Bone and dental support
Gardening fertilizer
Natural cleaning powder
Coffee maker descaling
Calcium-rich homemade supplements (when properly prepared)
This recipe teaches the safe preparation of boiled eggshell powder so you can use it confidently at home.
INGREDIENTS
6–12 eggshells (from boiled or raw eggs)
Water for boiling
Optional: lemon juice (for extra sterilization)
Optional: clean kitchen towel or baking tray
INSTRUCTIONS
Wash the Eggshells
Rinse each shell thoroughly under warm water.
Remove the inner membrane if possible (it peels off easily after boiling).
Boil for Sterilization
Place the shells in a pot and cover with water.
Boil for 10 minutes to kill bacteria like Salmonella.
Optional:
Add 1 teaspoon lemon juice to help remove any remaining membrane.
Drain & Dry
After boiling:
Drain the water
Place shells on a clean towel or baking tray
Let them air-dry for several hours, or use one of these methods:
Sun dry for 1–2 hours
Oven dry at 200°F (90°C) for 10–15 minutes, until completely crisp
Grind to Powder
Use a:
Blender
Coffee grinder
Mortar & pestle
Grind until the shells become a very fine powder, almost like flour.
Store
Keep in:
Airtight jar
Cool, dry place
Shelf life: 6–12 months
USES OF BOILED EGGSHELL POWDER
Natural Calcium Supplement (Food Safe)
Add ½ teaspoon to:
Smoothies
Soups
Oatmeal
Tea
Provides about 400–500 mg calcium per teaspoon
Supports bone strength
Helps calcium deficiency
Strengthens nails
Coffee Maker & Kettle Descaler
Add a spoonful of powder + water and boil.
Rinse afterward — removes mineral buildup naturally.
Skin Exfoliating Scrub

Honey
Aloe vera
Yogurt
Creates a gentle mineral-rich scrub.
Garden Fertilizer
Sprinkle around plants to:
Enrich soil
Prevent blossom-end rot in tomatoes & peppers
Deter slugs (sharp edges)
Teeth Whitening Paste (Mild)
Mix with coconut oil + baking soda.
Brush once weekly for enamel support (gentle only — not a bleaching agent).
Pet Calcium Supplement
Add a pinch to:
Dog/cat food
Bird feed
Great for bone and eggshell strength (for birds).
TIPS
Boil the shells every time, even if they came from boiled eggs
Grind finely — large pieces are not digestible
Use shells from organic/free-range eggs when possible
Add to acidic foods like lemon or yogurt for better absorption
For gardening, coarser powder works fine
Store in a glass jar for longest shelf life

Bones
Teeth
Nails
Muscle function
Zero Waste
