Why does cilantro taste like soap to some people?

A genetic variation in the OR6A2 olfactory receptor makes cilantro's aldehydes smell soapy to roughly 4–14% of people depending on ancestry — it is not a preference, it is biology.

Cilantro for heavy metals — does it work?

Cilantro juice has long folk and some animal evidence for binding certain heavy metals (especially mercury and lead). Human evidence is limited; treat as gentle support, not detox medicine.

Coriander seed vs cilantro leaf — different effects?

Yes. The seed is warming and digestive (used in CCF tea and bread). The leaf (cilantro) is cooling and cleansing. Persian medicine uses each for different patterns.
