We can find natural salt lamps being sold in most shopping malls as there is this belief thatthese lamps have the ability to improve the quality of air by enriching it with 'Negative Ions" and ionized air which is beneficial to humans. On the other hand, I do remember reading in one of Lilian Too's books that these lamps are not too good for us and would leave us lethargic and drained. Therefore I am not too sure about the lamps. I wonder whether anyone has done any research on the effects the salt lamps have on humans.
