Kuisia is a small, erect, glabrous and branching shrub, growing to 1.5 meters high. Leaves are glossy green, opposite, up to 3 centimeters long, petioled, ovate, with a rounded tip. Flowers are in clusters, fragrant, bright yellow, up to 1.5 centimeters across, in clusters of 4 to 6 at the stem tips.

– Popularly cultivated in towns and cities.
– Makes a good hedge plant.
– Flowers year-round.
– Native to Mexico.
• No reported folkloric medicinal use in the Philippines.
• In Latin American traditional medicine, used for asthma and allergies.
• In Mexican traditional medicine, used for mental disorders, as a sedative and tranquilizer.
• Homeopathic Proving: Statistical analysis showed no significant differences, certain symptoms were observed, i.e., relaxing, sedative, anxiolytic and anti-allergic. Results confirmed toxicological and clinical effects of Galphimia glauca compared to placebo, but not enough to satisfy the ICCH criteria for distinguishing between specific and unspecific symptoms.
Bronchoconstriction inhibition / Asthma:The ethylacetate fraction of the aerial parts significantly and selectively inhibited the bronchoconstriction induced by leukotrine D4 (LTD4).
• Anxiolytic / Galphimine B: Study has yielded an active principle, galphimine B (GB, a nor-seco-triterpene). Aqueous extract of Gg showed anxiolytic effectiveness, similar to that produced by lorazepam, but with regards side effects, Gg showed a higher tolerability than lorazepam.
• Anxiolytic / Galphimine B: Study evaluated the anxiolytic effects of galphimine B, A and E. Results showed the GRF (galphamine-rich fraction) had activity similar to the most active pure glaphamines, and the main determining factor for anxiolytic activity was the presence of free hydroxyl groups at C4,6,and 7 and the double bond A ring.
• Anxiolytic / Friedelanes: Studies have isolated the anxiolytic and sedative principle consisting of a mixture of norsecofriedelanes, named the galphimine series.
• Hay Fever / Pollinosis: Study comparing Galphimia glauca to placebo in the treatment of pollinosis showed a significant superiority of Gg over placebo, with effects comparable to those of conventional antihistamines but with no side effects.
• Toxicological / Cytotoxic: Study of extracts have yielded different triterpenes: galphimines. Galphimine B possess anxiolytic activity and selectively inhibits dischargers of dopaminergic neurons in rats. This study saw no deaths, no histopath changes; behavioral parameters showed a diminution of spontaneous activity. All the extracts inhibited colon cancer cell line growth with no genotoxic effect.
• Phytochemicals / Weak Anti-Protozoal Activity: Study isolated four new terpenoids with the known sterols and flavonol quercetin. Quercetin was the only isolate that showed any antiprotozoal activity, and weak at that.
• Generalized Anxiety Disorder / Clinical Trial / Comparison with Lorazepam: Study of G. glauca herbal medicinal product, standardized in 0.175 mg of glaphimine-B and administered for 15 weeks to patients with generalized anxiety disorder, showed greater anxiolytic effectiveness compared with lorazepam, with a high percentage of therapeutic tolerability and safety.
