Really shocked to see this product contains borax,boric acid and potassium nitrate used in fertiliser. Borax is used in cleaning products. Thought I could trust Weleda products now I am not so sure. I just wanted the herb eyebright which can no longer be bought in NZ since our pharmaceutical controls banned it from sale. I used to use the dried herb for eye problems and it was excellent. Now all these additives sold in the product which are poisons. Sigh! *** SUPPLIER RESPONSE: When used as directed on the product label, Euphrasia 3x Soothing Eyedrops soothes irritated eyes. The inclusion of potassium nitrate, boric acid and the borate salt in the product controls the pH and salinity at levels that make it comfortable when applied to the eye. This is achieved by including them at very low concentrations. They are internationally approved ingredients for use in eye medicines, including by the European and New Zealand Medicines agencies and are commonly used in eye drops, artificial tears, etc. We are not aware of any sensitivities to this product.
