My son was doing great with Chlorophyll, one of the greatest benefits I love about this supplement is it helps to raise hemoglobin. One of the main issues my son was having was his hemoglobin would drop as low as 6, which is very dangerous and he would need a blood transfusion. Every doctor appointment we had there after, his hemoglobin was always over 8.4, which is really good for a sickle cell child. I knew then, the Chlorophyll was working!!! Eight months later, in November of 2011, he had his first pain crisis in his joints; his leg was in sever pain for 2 weeks. Back to the drawing board I went. Sometimes one herb alone may not solve all the issues, so I researched herbs that promotes healthy blood circulation, although Chlolrophyll does help with blood circulation, I needed something else to work in conjunction with Chlorophyll. I discovered Gingko Biloba, this herb improves blood flow to the brain and throughout the body, there is some evidence of it protecting against the effects of strokes. Strokes are very well known to occur in sickle cell patients. I started giving him Gingko Biloba in November 2011 and so far so good, no more pain crisis as of today.
