Arnica Dosage for healing brain afetr brain Stroke and haemmorrage?

I read section from a blog posted on Internet site

" Whenever a person has been injured, not only the acute effects but even the chronic effects of this injury can be removed by Arnica, whatever its nature may be” (YEAR). Sankaran discusses a case where a man lost vision in his eye after an accident. Sankaran put the man on the following protocol, and the gentleman slowly regained his vision: Arnica 30C TID X 1 month; Arnica 200C QD X 5 months; Arnica 1M QD X 2 months (YEAR). A second case describes a 61-year-old woman who suffered a TBI from a scooter accident. She had been semi-comatose for 9 days and doctors were discussing brain surgery. Sankaran gave this woman Arnica 200C hourly for 48 hours, at which point she was 50% better. He continued Arnica 200C every hour for 2 more days. Lastly, he gave Arnica 1M hourly until it was discontinued on day 12, when her catheter was removed (YEAR).

I had the personal experience of speaking with a homeopath in India who told me of a case of a man with a TBI that he brought out of a coma with a simultaneous single dose of Arnica 200C and Natrum sulphuricum 200C."
