While not a replacement for medical treatment, eggshell powder is a traditional, bioavailable source of dietary calcium.
- How to use: Bake clean, dry shells at 200°F for 10 mins, grind to a fine powder, and add a ¼ tsp to smoothies or oatmeal (consult your doctor first—especially if you have kidney issues).
🐜 3. Say Goodbye to Garden Pests—Naturally
Crushed boiled eggshells create a sharp, abrasive barrier that deters soft-bodied pests like slugs and snails.
- How to use: Sprinkle coarsely crushed shells around vulnerable plants—no chemicals needed!
🧴 4. Say Goodbye to Wasted Kitchen Scraps
Eggshells can even be used in gentle DIY scrubs or toothpaste (use food-grade shells only).
- Caution: Never use raw eggshells on skin or teeth without sterilizing them first by boiling or baking.
✅ How to Safely Prepare Eggshells
- Rinse well to remove membrane residue.
- Boil for 10–15 minutes to kill bacteria (especially important for garden or consumption use).
- Dry completely—overnight or in a 200°F oven.
- Crush or grind as needed.
⚠️ Important Notes
- Do not eat eggshells raw or unsterilized—risk of salmonella.
- For plants: Eggshells break down slowly—best used as a preventative, not a quick fix.
- For health: Always talk to your doctor before using eggshell powder as a supplement.
💛 The Bottom Line
Eggshells aren’t waste—they’re a free, renewable resource full of potential. By boiling and repurposing them, you honor the whole egg, reduce trash, and support your garden and health the old-fashioned way.
So next time you crack an egg, save the shell. Your plants—and maybe even your bones—will thank you. 🥚🌿
