I noticed a few things that don't make sense to me though. He suggests taking 75,000 units a day of vitamin A(perhaps that is typo?). That seems extremely high to me, and long term intake of that much vitamin A might lead to toxicity. A more conservative absolute upper limit for long term vitamin A supplementation is imo 25,000 units a day.
He also says that licorice root is not antifungal, although several other articles I read said that it has many antifungal compounds in it.
He also claims it is okay to take tea tree oil internally as long as it doesn't say for external use only. Most other websites warn against taking tea tree oil internally.
He also recommends using colloidal silver, while imo it is too risky to use, especially for those who have heavy metal toxicity.
