I came to know from my colleague  that Kulekhara (Hygrophila Spinosa) leaf  increase hemoglobin. She, suffering low Hb but not for thalassemia,  takes kulekhara leaf juice and improve her Hb rapidly. She took Ayurveda medicine Kulerron   http://www.branoliachemicals.com/kulerron/   as well as leaf juice.
Anybody know about Kulekhara for thalassemia patient.
