My Son (29 Years Of Age) Had A Severe Accident

My son (29 years of age) had a severe accident and suffered from compartment syndrome. muscle and tissue was removed from his calf and arm. He is also blind in his right eye. He's coming home on Thursday from rehab and can't move his hand up and has drop foot. In fact, he can barely walk with a walker. What's your perspective on Korean Ginseng and nerve growth?
