It looks like that sentence is from a clickbait tip that usually ends with something like:
“Stop throwing eggshells away. Boil them and say goodbye to pests / calcium deficiency / bad soil.” 🥚
Here are the most common things people actually do when they boil eggshells:
1️⃣ Natural calcium water for plants 🌱
Boiling eggshells releases some calcium into the water.
How to do it:
- Rinse the eggshells.
- Boil them in water for about 10 minutes.
- Let the water cool overnight.
- Use the water to water plants.
Why:
Calcium helps plants prevent problems like blossom-end rot in tomatoes and peppers.
2️⃣ Garden pest deterrent 🐌
After boiling and drying the shells:
- Crush them into small sharp pieces.
- Sprinkle around plants.
Effect:
The rough edges can discourage slugs and snails from crawling over them.
3️⃣ Homemade calcium powder for soil 🪴
- Boil eggshells to sanitize them.
- Dry them completely.
- Grind into fine powder.
- Mix into soil.
This slowly adds minerals and calcium.
4️⃣ Mild mineral drink (less common) 🥤
Some people boil eggshells in water and drink the cooled water for trace calcium.
However, the calcium amount is very small, so it’s not a reliable supplement.
✅ Bottom line:
Boiling eggshells is mainly used to sanitize them and extract minerals, mostly for plants and gardening.
