Don't trust, verify. Whenever a medicine is recommended look into the sources to see if the data supports it's use. There is too much bullshit in the mainstream, but there is beneficial science buried among it as well. Don't throw out the baby with the bath water, dismiss unverified medicine unless you understand it enough to trust it based on your own research.
FIAT has corrupted everything, science and medicine included. But real science and medicine is still out there, and will reveal itself to those who spend the time to verify it for themselves.
