After participating on a focus group on long covid brain fog earlier this week I was reminded how helpful herbs can be. Often, they can turn symptoms around in 1-2 weeks which makes a huge impact on how my patients feel. Here are three of my favourites:
Lion's Mane (Hericium erinaceus)
Lion's mane mushroom is known for its potential to enhance cognitive function and support brain health. Research suggests it may boost nerve growth factor production, which supports the survival and growth of neurons to improve thinking, memory, and overall cognitive performance.
Saffron (Crocus sativus)
Saffron has demonstrated neuroprotective and cognitive-enhancing properties.. Saffron’s active compounds (crocin, crocetin) reduce oxidative stress, neuroinflammation, and prevent neuronal cell damage which are all factors associated with "brain fog" and diminished cognitive function. Evidence also indicates saffron helps modulate brain inflammation and improves mood and anxiety, supporting clearer thinking.
Holy Basil (Tulsi, Ocimum sanctum)
Holy basil is classified as an adaptogen and it helps the body adapt to stress, a major cause of “brain fog.” Its compounds (like rosmarinic acid and eugenol) lower cortisol levels, calm the nervous system, and enhance blood flow to the brain, supporting improved focus and reduction of mental fatigue. Regular consumption is linked to reduced anxiety, greater mental clarity, and better memory and learning.
If you need help recovering from long covid or any other viral infection, please get in touch to find out more.
