Origin & History

Natural habitat

Maoto is a traditional Japanese Kampo formula derived from the Ephedra plant. It is prepared by decocting the stems and leaves of the Ephedra plant along with other herbs.

“Maoto has been used in traditional Japanese medicine for centuries as a remedy for cold and flu symptoms. It is part of the Kampo medicine system, which integrates Chinese herbal knowledge with Japanese practices.”Traditional Medicine

Research Narrative (Provisional)

Some studies, including randomized controlled trials, have shown that Maoto can be effective in reducing the duration and severity of cold symptoms. However, more research is needed to fully understand its efficacy and safety profile.

The presence of tannins may slightly inhibit the absorption of certain minerals."}

Reported Mechanism (Provisional)

Mechanism of Action

Ephedrine in Maoto activates beta-2 adrenergic receptors in bronchial smooth muscle, causing bronchodilation and improved airflow. Cinnamaldehyde from cinnamon bark inhibits inflammatory cytokines like TNF-alpha and IL-6. Glycyrrhizin from licorice root modulates cortisol metabolism and enhances anti-inflammatory corticosteroid activity.

Clinical Narrative (Provisional)

A randomized controlled trial of 104 patients showed Maoto reduced fever duration by 1.2 days compared to standard care for influenza A. Another study of 67 subjects demonstrated 40% faster recovery from cold symptoms within 5 days. However, most clinical evidence comes from small Japanese studies with limited Western population data. More large-scale international trials are needed to confirm efficacy across diverse populations.
