Herbal Therapy: Green Tea and Its Bioactive Epigallocatechin gallate (EGCG) in Ameliorated Risk, Progression and Treatment of Amyotrophic Lateral Fclerosis (Lou Gehrig's disease)

Green tea may have a therapeutic and positive effect in reduced risk, progression and treatment of amyotrophic lateral sclerosis (ALS), some scientists suggested.

Green tea is a precious drink processed numbers of health benefit and known to almost everyone in Asia and Western world.

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a specific disease involved the death of neurons in controlling voluntary muscles.

According to the research published by the Hanyang University, administration of green tea Epigallocatechin gallate (EGCG) exerted a neuroprotective effect in reduced oxidative stress in orchestrated death of neurons.

In the evaluation of green tea EGCG in risk of amyotrophic lateral sclerosis (ALS) in human G93A(with function in responsible for destroying free superoxide radicals in the body) mutated Cu/Zn-superoxide dismutase (SOD1) gene in mice model, scientists found that

application of green tea EGCG at doses of 1.5, 2.9, and 5.8 microg/g body weight, dissolved in 0.5 ml of 0.9% sterile NaCl intraorally every day after 60 days of age demonstrate significant effects in prolonged the symptom onset  and life span of ALS mice through preserved more survival and attenuated death signals.

The result of increased life span of mutated gene mice was attributed to increased antioxidant activity of green tea in inhibited the levels of ROS in reduced cytotoxicity in initiated death of neurons in controlling voluntary muscles.

Further analysis of the effect of green tea in mutated SOD1-G93A in transgenic mice and wild-type mice randomly divided into EGCG-treated groups (10 mg/kg, p.o) and vehicle-treated control groups to assess the motor function, starting at the age of 70 days researchers found that injection of green tea treatment mice display a strong effect in delayed the onset of disease, and extended life span, similar to those in the Hanyang study.

Additional differentiation also indicated that green tea treatment group stimulated the production of numbers of new motor neurons in compared to control mice,

Interestingly, the application also decreased the over expression of microglial activation in initiated the inflammatory response due to neuronal damage and removed the damaged cells caused by phagocytosis production.

Prolonged and over expression of inflammatory cytokines may increase risk of neuron damage and in some cases death of the nerve cells.

Researchers in depth analysis showed that green tea reduced immunohistochemical reaction of NF-kappaB in response to the neuron damage (by antigens) through stimulated production of pro inflammatory factors (as antibody) and cleaved caspase-3 in induction of neuron apoptosis.

Moreover, application of green EGCG also expressed a similar result as in other studies in decreased protein level of iNOS and NF-kappaB in the spinal cords in orchestrated free radical NO levels and  inflammatory cytokines in neuron cell death in the spinal cord involving the onset of ALS.

Dr. Xu Z, the lead author after taking into account of other co founders said, "this study provides further evidences that EGCG has multifunctional therapeutic effects in the mouse model of ALS".

These result were supported by the study of the green tea effect in risk of Lou Gehrig's disease through reviewing the food selection of 44-item food frequency questionnaire of 1 million men and women enrolled and conducted in 1989 through 2002 for ALS mortality.

According to results of the study, researchers at the Harvard School of Public Health suggested that green tea injection is associated to reduced mortality rate of patients.

The information findings suggested that green tea and its bioactive polyphenol Epigallocatechin gallate (EGCG) may be considered as a function food for reduced risk and used combination with standard medicine in delayed progression and treatment of Amyotrophic lateral sclerosis (ALS).
