I don't know about expectorants but slippery elm is helpful, soothing for leaky gut. One supplement called Perm-A-Vite used to help cure leaky gut has the following ingredients:
Cellulose, Glutamine, Acetyl-D- Glucosamine (shrimp, crab, lobster), Slippery Elm (Ulmus rubra) (Bark) Powder, Stevia (Stevia rebaudiana) (Leaves) Extract, Glandular Complex with Epithelial Growth Factor, MSM (Methylsulfonylmethane)
