A good a time as any to repost a piece I did on this blog about a year ago.
It turns out that components in tawa-tawa actually inhibit platelet aggregation. This could be useful in other diseases, but this isnt what you want when you have DHF. You want your platelets aggregating. It may be fortunate that the decoction of tawa-tawa given to DHF patients doesnt have the concentrated amount of the platelet suppressants that the extract form contains, or else it may have done more harm than good.Like I said, the evidence for the efficacy of tawa-tawa presented in the articles by Aspiras and Yuson, and the blog post by Zafra are anecdotal. Although I do hope that there is indeed something in tawa-tawa that alleviates the symptoms of DHF, at this time I strongly suspect that the evidence presented are of the post hoc ergo propter hoc variety. Person had DHF, person takes tawa-tawa tea, person feels better. Ergo, tawa-tawa cures DHF.
Still no studies are being cited. (Oh, wait. 'Studies' are being cited. Unnamed and unattributed mystery studies, that is.) No clinical test results. Nothing.
We need these studies. For all we know, E. hirta is the medical breakthrough the world has been waiting for, or is just a poppycock potion. We either confirm it as a cure (or at least a palliative) or junk it altogether. Either way, we need it confirmed scientifically. Don't these hospitals like St. Luke's and Makati Med which none of us can afford have labs? Surely they'd have the wherewithal, the facilities, and the personnel to take the lead in this.
In the meantime, 2.5 billion people worldwide remain at risk.
