No, a salt lamp is not edible.
Why You Should Not Eat Salt Lamp Salt
While salt lamps are made from natural salt crystals, the salt used in them is not intended for consumption. The primary reason you should not eat the salt from a lamp is that it is not certified as food grade.
According to experts, the salt in your lamp might have arsenic or other deadly minerals in it. These substances would not affect the lamp's function but would certainly affect you if consumed.
- Potential Toxins: Salt extracted for industrial or decorative use, like in salt lamps, can contain impurities or minerals that are harmful when ingested, such as arsenic.
- Lack of Certification: Unlike table salt or food-grade mineral salts, salt lamp salt does not undergo the rigorous purification and safety checks required for food products. You should eat minerals ONLY when they are certified as food grade.
- Intended Use: Salt lamps are designed purely for lighting and decorative purposes, not for human consumption.
Therefore, based on the potential presence of harmful minerals and the lack of food-grade safety certification, YOU SHOULD NOT EAT the salt from a lamp.
