Garlic and onions do have some compounds in them that affect the red blood cell count in dogs and can cause anemia. I don't know about chameleons.
If I was going to go "natural remedy" I would look into papaya seeds as gut load for worms. I have used it but I don't know if it is effective yet. It has not caused other problems so far. It can be gut irritant so I don't feed it directly.
