Never drink HOCl. While it has been used as a mouthwash, swallowing a quantity of HOCl could kill friendly bacteria and viruses in the GI Tract causing long-term GI Tract issues or worse.
While HOCl can be used to treat wounds and is used in surgery to the depth of the bone, it cannot be injected into the body to kill infections.
When treating eye infections, speak with a doctor before beginning treatment to verify whether the infection can be cured with HOCl alone.
