Verified Fact-Checks

Moderate Evidence 70% Trust
"Giloy cures dengue."

Truth: Giloy may possess anti-viral properties that can help reduce dengue symptoms, but it is not a standalone cure for dengue.

Research Ongoing 60% Trust
"Neem cures cancer."

Truth: Certain components of Neem have shown anti-cancer properties in laboratory and animal studies, but further intensive research on humans is required for it to be an effective treatment. It should not be used as a substitute for conventional medical treatment.

Moderate Evidence 70% Trust
"Aerva lanata immediately breaks kidney stones."

Truth: Aerva lanata possesses properties that help dissolve and expel stones, but claiming it 'immediately breaks' them is an exaggeration. It depends on the type and size of the stone.

No Reliable Evidence 10% Trust
"Aloe vera cures cancer."

Truth: Aloe vera may possess some anti-cancer properties as demonstrated in laboratory studies, but it is not a cure for cancer and there is insufficient reliable scientific evidence to prove its effectiveness in humans.

Limited Evidence 60% Trust
"Eating guava cures diabetes completely from the root."

Truth: Guava can help regulate blood sugar levels, but it cannot cure diabetes completely from the root. It is a supportive measure, not a cure.
