Tracing the geography of thalassemia, there seems to be a 'founder effect' endemic region in Iran. One would note these connections to camel grass (Cymbopogon schoenanthus). Its biochemistry is inadequately documented, yet flavonoid chemistry obviously applies here to thalassemia. In addition, note Shanidar Cave, which may coincide to the founder effect area.
