Battling Cancer With Capsaisin

A new study suggests that capsaicin can make prostate cancer cells commit seppuku:

The same component of jalapeño peppers that makes them burn the tongue also appears to kill prostate cancer cells. Prostate tumours in mice treated with the compound, called capsaicin, shrank to one-fifth the size of those in non-treated mice, found a new study.

To explore capsaicin’s effect, Phillip Koeffler of the Cedars-Sinai Medical Center in Los Angeles, US, and colleagues exposed human prostate cancer cells in a laboratory dish to the natural compound. They found that capsaicin dramatically slowed the proliferation of the cells in the dish.

He believes that capsaicin jump starts a pathway that triggers cell death. Molecular tests suggest that it achieves this by causing a cascade of events inside the cell that lead to the release of a protein complex called NF-kappa Beta, which subsequently causes the cell to self-destruct.


Unfortunately, these effects require rather high dosages:

He adds that one also must take dosages into consideration. A 200-pound (90-kilogram) person would have to eat about 10 fresh habañera peppers – one of the hottest chillies around – per week to consume an amount of capsaicin equivalent to the levels received by Koeffler’s mice.

Now that's a challenge!
