If you’re referring to the common “boil eggshells and say goodbye to…” tip, it’s usually promoting ways to reuse eggshells instead of throwing them away. Eggshells are mostly calcium carbonate and can be useful around the home, but some viral claims exaggerate their benefits.
Here are some practical uses:
- Garden soil amendment: Crushed eggshells can add calcium to soil and may help improve soil structure. They break down slowly, so they are not an instant fertilizer.
- Compost addition: Clean, crushed shells can be added to compost.
- Cleaning abrasive: Finely crushed eggshells can help scrub some surfaces when mixed with soapy water (avoid delicate surfaces).
- Crafts: Clean, dried shells can be used for decorations and art projects.
If you boil eggshells:
- Rinse shells to remove egg residue.
- Boil them for several minutes to reduce bacteria.
- Let them dry completely.
- Crush them before reuse.
Claims that eggshell water can “cure diseases,” “replace supplements,” or solve major household problems are generally not supported by good evidence. For calcium supplementation or health concerns, it’s better to use proven sources and speak with a healthcare professional if needed.
