Does this say by 'efficiently' delivering phytic acid they are able to cure Sickle Cell in the mouse ?
They mix it externally and then inject into the mice.

Abstract
Summary
Patients with sickle cell disease (SCD) can present several severe
symptoms during their lifetime, including painful events due to
vascular occlusion (VOC).
Even though multiple factors are involved in VOC, hypoxia is the most
important triggering factor.
Inositol hexaphosphate (IHP) reduces the oxygen-haemoglobin affinity
thus improving the oxygen release in the blood stream and in the
tissues.
Thus, IHP-loaded homologous red blood cells (IHP-RBCs) could be able
to reduce disorders in SCD.
The effectiveness of treatment was assessed in two types of SCD
transgenic mice (BERK and SAD).
The administration of four repeated injections of IHP-RBCs in BERK
mice resulted in an improved survival rate and brain development,
prevention of severe anaemia and a greatly lowered risk of VOC.
After one injection of IHP-RBCs, SAD mice were subjected to acute
hypoxic stress.
Analysis of the lungs revealed significantly decreased mRNA levels of
molecules involved in intravascular disorders.
Our results showed that transfusion of homologous IHP-RBCs, by
increasing the oxygen delivery, reduces SCD disorders in sickle
transgenic mice.
