Milan purchased saffron extract, marketed as Americas Hottest New Way to a Flat Belly, online from Dr. Chen. The website stated that recently published studies showed a significant weight loss (more than 25 percent) for people who used pure saffron extract as a supplement without diet or exercise. Dr. Chen said that the saffron suppresses appetite by increasing levels of serotonin, which reduces emotional eating. Milan took the extract as directed without any resulting weight loss.

Question:

-Determine and explain whether Dr. Chens website made any express warranty on the saffron extract or its effectiveness in causing weight loss.
