7. Why the “One Herb Cures Everything” Claim Can Be Misleading
Parasites, bacteria, and viruses are biologically different. Even within these categories, different organisms behave differently and respond to different treatments.
A substance that affects bacterial growth may have no meaningful effect on a virus. An extract that interferes with a parasite in a laboratory dish may not be absorbed adequately when swallowed.
The dose also matters. A small amount in food may be safe, while a concentrated supplement or essential oil may cause harm.
There is another challenge: herbal supplements can vary in quality, concentration, and purity. Some may contain ingredients that differ from those listed on the label, and some can interact with prescription medicines.
This does not mean that all herbal remedies are useless. It means that claims should be evaluated individually and supported by reliable evidence.
A useful question is not simply, “Has this herb been shown to kill a microorganism?” It is also, “Has this particular preparation been tested in people, at what dose, for which infection, and with what results?”
