Thank you for your response.
I suggest eliminating all foods that he's sensitive to. Ask his doctor to write a prescription for a Nebulized inhaled glutathione that a compounding pharmacist can make. you should have each day’s
glutathione prepared in its own separate vial as glutathione when exposed to the air it loses it's potency. the prescription should be 120-200
milligrams per inhalation. he should also take 500 milligrams of
N-acetylcysteine three times per day you can buy it at any health food store.
It will help to keep the secretions of the bronchial loose.
