Licorice root (Glycyrrhiza glabra) has a long history of use in traditional herbal medicine systems, particularly in Ayurveda and Traditional Chinese Medicine (TCM). In these systems, licorice root is considered to harmonize and enhance the effects of other herbs, and is often used to support digestive health, reduce inflammation, and address symptoms like indigestion and ulcers. The Solar Plexus, or Manipura chakra, is associated with the digestive system and personal power in various holistic and energetic frameworks. Herbalists who work with energetic body systems often recommend licorice root for balancing the Solar Plexus due to its reputed soothing effects on the digestive tract and its role in alleviating stress-related digestive disturbances. However, the connection between licorice root and the Solar Plexus is based on traditional energetic concepts rather than on scientific studies specifically investigating this association.

While there is some scientific evidence supporting licorice root's effects on the digestive system—such as its potential to soothe gastric mucosa and reduce inflammation—there is limited to no scientific literature directly linking licorice root to the "Solar Plexus" as described in energetic or chakra-based systems. Thus, while its use is justified by tradition, especially within herbal and holistic frameworks, scientific validation for this specific energetic use is lacking.
