Looking for natural ways to support mental energy and manage stress? According to Dr. Terry Shintani, MD, a Harvard-trained physician and nutritionist, these five herbs are among the most well-studied for brain and stress support.
1. Sage
As its name suggests, sage has long been used to enhance brain power and memory. Research suggests one of its effects is as an acetylcholinesterase inhibitor — meaning it helps preserve acetylcholine, a neurotransmitter important for brain energy and memory.
2. Rhodiola
Rhodiola is thought to help by managing neurotransmitters such as norepinephrine, serotonin, and dopamine — all involved in mood and mental energy.
3. Ashwagandha
This adaptogenic herb helps control cortisol levels and may modestly increase testosterone, supporting the body’s resilience to stress.
4. Holy Basil (Tulsi)
Holy basil also helps regulate cortisol levels, making it another helpful tool for managing stress.
5. Siberian Ginseng (Eleuthero)
Also known as eleuthero, this herb contains compounds called eleutherosides, which appear to boost mental energy by increasing oxygen utilization in the body.
The takeaway
These five herbs work through different pathways — some by supporting key brain neurotransmitters, others by helping regulate the body’s stress hormone, cortisol. For a fuller list of stress-support herbs and more natural health tips, get Dr. Shintani’s free eBook, Health Secrets, at peacediet.org.
