When used as a treatment, licorice can be found in a wide variety of formulations, including but not limited to tablets, powder, drops, chewables, capsules, tea, dried root infusions, decoctions, syrups, tinctures, and gum. It’s also found in a wide variety of candies, foods, beverages, and even cigarettes as a flavoring agent.^[12] The glycyrrhizin content of licorice products varies by the species and origin of the raw licorice root; according to one study, it can range from from 0.3–8.3% (with an average around 3.3%), but other studies have cited it as high as 6–10%.^[13][14] Deglycyrrhizinated licorice is also available, and it has been processed to reduce glycyrrhizin content below detectable levels.

To treat ulcers and gastritis, daily dosing can range from 1–15 grams.^[15] However, it should be noted that individual characteristics (sex, age, health status, etc.) and how the root has been prepared may affect its action or potency.^[15][1][16]

Traditional Chinese Medicine recommends 8–15 grams of licorice extract for general health and up to 100 grams for use in health conditions, but it is commonly found combined with other ingredients in this context.^[1] The components of licorice appear to interact with other nutrients, typically in a synergistic manner. When combined with lycopene, it may work synergistically to prevent LDL oxidation.^[17] If taken alongside oriental bezoar and Panax ginseng, it is thought to synergistically reduce stress-induced biomarker changes.^[18][19] Combining licorice with cranberry may confer a synergistic anti-inflammatory and antibacterial effect.^{[20][21][22][23]}
