![]() ![]() ![]() A quirk of nature it might seem, but the heritage of those with the distinctive trait doesn't point to just one isolated corner of the earth-parentage ranges from Brazil to Jamaica to Ghana.īoth parents need to be carriers of the recessive MC1R gene in order for a child to be a redhead, so I wondered whether it had been passed down and across through centuries of human migration, the slave trade and even Irish/Scottish indentured servitude in the British Caribbean in the 17th century. However, there's no concrete data and a distinct lack of research on the ethnicity behind those with red hair. Compare this with the world's population, where 1 to 2 percent is thought to be redhead, and redheads from ethnic minorities are even rarer. It's estimated that in Scotland, 13 percent of the population have ginger hair. "I'm hoping that with these pictures that reflex changes a bit." "To make sense of what's around us we put people in boxes-it's a natural reflex and is not intended in a malicious way," says Lyon-born Michelle, who finds her participants on social media, through recommendations or in passing in a packed shopping center. It'll either work "properly," causing your hair to get darker, or it will become dysfunctional, not activate, and then fail to turn red pigment to brown, causing a build-up of red pigment and thus, red hair. Mutations in it can cause various degrees of pigmentation. Selective PDE5 inhibitors are good pro-erectiles without many side-effects, but the non-selectivity (currently not established) may lead to gastrointestinal side effects.Īt least one study has noted that it can increase functionality and cardiovascular performance in otherwise healthy persons over 60, but an acute study in youth failed to find any performance enhancing effects at 1.35g (recommended dose, or at least near it).Ĭurrently, Thai Ginseng seems to be weakly promising on proerectility with the other claims not really being better than other possible supplement choices.MC1R, or Melanocortin 1 receptor if you're feeling fancy, is the gene responsible for red hair. The mechanism of pro-erectility is fairly unique and interesting, but the one study to investigate whether or not it could inhibit PDE5 (one of the mechanisms of Viagra) failed to establish whether it was selective. It does not appear to increase testosterone in otherwise normal rats (although it may in castrated rats), and although it appears to have a variety of mechanisms to be pro-erectile, these have not been tested for potency in a living system. That being said, the research on its aphrodisiac effects in mice indicate that low doses are weak to moderate in potency and higher doses fail to exert any aphrodisiac effect. ![]() It appears to be 'healthy' and a good source of a class of bioflavonoid compounds with methoxy groups added to them, known as methoxyflavones. It is also reported to be an aphrodisiac compound and physical enhancer.Ĭurrently, the research on Thai Ginseng is at a moderate level and starting to get human trials. Kaempferia Parviflora (Thai Ginseng) is a herb that has some historical and medicinal usage for treating metabolic ailments and improving vitality in Thailand and limited to surrounding regions.
