Black galingale (in Thai krachaidam) is a medicinal plant in the family Zingiberaceae and can be found in tropical areas such as Thailand. Its rhizome has been long used as folk medicine for many centuries.
Among the Hmong hill tribe, black galingale is widely believed to reduce perceived effort, improve physical work capacity, and prolong hill trekking. A number of pharmacological studies of krachaidam have shown the following properties: antiallergenic, anti-inflammatory, antimutagenic, antidepressive, anticholinesterase, antimicrobial, anticancer, antipeptic ulcer, cardioprotective, antiobesity activity and aphrodisiac.
For erectile response outcome it showed that subjects receiving Krachaidam 90 mg/day exhibited a significant enhancement in all parameters (ie, response latency time to visual erotic stimuli, size and length of penis both in flaccid and erectile states) after 1 and 2 months of treatment compared with placebo. The authors explained that the effects involved nitric oxide. The experimental studies reported that Krachaidum extract could induce an increase of endothelial nitric oxide synthase and protein expression in human umbilical vein endothelial cell. Thus, abundance of endothelial nitric oxide synthase in endothelium of penile vasculature and sinusoidal endothelium within the corpora carvernosa might increase penile erection.
