some research i am doing on essential oils and vasodilation
rosemary and menthol are not potent, neither is euclayptus, neither make the top 10
patchouliguaiols ,
citral,
carvacrol + thymol ,
eugenol
are the most potent vasodilators if you are looking at isolated chemicals
for patchouliguaiols, spikenard or simply patchouli oil would work
for citral, lemongrass or lemon verbena
for carvacrol + thymol , - oregano and thyme
for eugenol - clove essential oil would work
ginger, cinnamon, capscium, rosemary, menthol don't make the top 10 list.
rosemary for hair is the biggest scam going, look at the science, the chemicals in rosemary do not vasdodilate,
