Please help correct it. It is unique because of its high concentration of natural minerals and "salt which has been used" over the centuries for cosmetics and beautification purposes. I'd like to know whether it's correct to use "has" here or not! Please help correct it. Thanks:)!

If you're talking about two or more things, "natural minerals and salt", then you should use "have been used" not "has". If you're just talking about one thing "salt", then "has" would be ok. Hope this helps. Sinead
