Perfect for oral care. Prevents bad breath and periodontal disease. Refreshing dental care. Simply rinse without dilution. No need to rinse with water afterwards. For those concerned about bad breath... It seems best to use it about twice a day, morning and evening. Please do not offer a discount. The cost of goods has increased, so the price is higher than before. I believe I am offering it at a lower price than anywhere else... I'm sorry, but I cannot offer a discount.
