In the study, published in BMC Complementary Medicine and Therapies, Polygala tenuifolia attenuated cognitive deficits by rescuing hippocampal neurogenesis.

Polygala tenuifolia provides mood support and has potential as an antidepressant. It's exciting to learn it may also promote neurogenesis, the process by which new neurons are formed in the brain.”

DENVER, COLORADO, UNITED STATES, November 18, 2021 / -- A study published on October 25, 2021, in BMC Complementary Medicine and Therapies revealed that a constituent of Polygala tenuifolia has the potential to reduce cognitive deficits. In the study, the constituent, 3,6'-disinapoyl sucrose (DISS), triggered a potent increase of hippocampal neurogenesis in a mouse model of Alzheimer's disease. DISS strengthened APP-neural stem cell proliferation and neuronal differentiation, and DISS treatment for four weeks showed the capability to attenuate cognitive deficits, neuronal injures, and neurogenesis disorder.

The study investigated the effects of DISS and two other active constituents of Polygala tenuifolia on the proliferation and differentiation of neural stem cells to identify the potential active constituent of Polygala tenuifolia that promote hippocampal neurogenesis. The study evaluated cognitive function, neural damages, and hippocampal neurogenesis.

Polygala tenuifolia is a traditional Chinese medicine with multiple neuroprotective properties. Alzheimer's disease is the most common dementia worldwide, and to date the disease lacks satisfactory drug or therapeutic strategies. Further clinical research is warranted, as Polygala tenuifolia may prove helpful in supporting Alzheimer's disease treatment.

Polygala tenuifolia extract is traditionally consumed as a health supplement to provide mood support, improve sleep quality, and heighten creative thinking. It has the potential to calm and relax the body by easing restlessness and anxiety. Its Chinese name, Yuan Zhi, translates to “high aspirations.”

Beyond cognitive support and mood support, Polygala tenuifolia has increasingly been used to support treatment of inflammation of the throat, nose, and chest and for lung conditions including asthma, chronic bronchitis, whooping cough, and emphysema. The root is considered antibacterial, cardiotonic, cerebrotonic, expectorant, haemolytic, hypotensive, sedative, and tonic.

“Buddhist monks use Polygala tenuifolia for meditation and focus, and we call it the Will Strengthener," says Linden Botanicals owner Michael Van der Linden. "Polygala tenuifolia provides mood support and has potential as an antidepressant. It appears to have adaptogenic action on cortisol, the stress hormone. What's most exciting, though, is that it may also promote neurogenesis, the process by which new neurons are formed in the brain.”
