The Truth About Nightshade Vegetables: But Capsaicin Is Healthful, Right?
That's debatable. Capsaicin appears to have some inhibitory effects on the healing process as well. Combine capsaicin from the peppers with the small dose of nicotine that comes from eating them and you can see how the healing process can be slowed. Capsaicin can actually be toxic in high doses and inhibits a part of the immune system that hunts down cancerous cells for up to 90 days! Epidemiological evidence shows that cultures that eat high amounts of peppers and tomatoes have higher incidences of cancers all throughout the digestive tract.
