I found this info from Dr Al Sears.
The Herb That Came in from the Cold
It’s called schisandra. And it increases your resistance to stress and disease, increases your energy, and boosts your endurance.20
Now I could walk you through page after page of my detailed research to show you precisely why schisandra boosts physical and mental performance.
I could explain how schisandra increases the exchange of oxygen in tissue cells… how it helps prevent respiratory acidosis… and how this boosts endurance.21
I could tell you how schisandra enhances memory and concentration its cholinergic function and by inhibiting acetylcholinesterase… which increases levels of the neurotransmitter acetylcholine which is vital for memory and attention span.22
Researchers tested schisandra on sailors keeping watch at sea. It was shown that the sailors were more alert after drinking a schisandra tea.https://marketing.alsearsmd.com/acton/media/28028/dc2837-nativerest-20190704?utm_term=You%5Cu2019re%20just%20one%20click%20away%20to%20renewed%20energy%5Cu2026&utm_campaign=6-second%20solution%20to%20your%20fatigue&utm_content=email&utm_source=Act-On+Software&utm_medium=email&cm_mmc=Act-On%20Software-_-email-_-6-second%20solution%20to%20your%20fatigue-_-You%5Cu2019re%20just%20one%20click%20away%20to%20renewed%20energy%5Cu2026&sid=TV2:oBmipdkBA
