I think ruby red grapefruit could work. But also, a lot of people, me included, can't have grapefruit because it has a negative reaction with a lot of medications, so maybe it's best they don't.
Huh interesting, had no idea. I sometimes take fexofenadine. I didn't know grapefruit could reduce its effectiveness. I'm glad I don't take any drug that interacts the opposite way with the grapefruit.
