You may just need a good Ashwagandha root

A study performed by Dongre S et al. demonstrated the ability of Ashwagandha (Withania somnifera) root extract to improve the sexual experience in women compared to placebo. Supplementation showed significant imporvements in “arousal”, “lubrication”, “orgasm” and “satisfaction”.

The article discussed potential mechanisms of action but interestingly the study showed how Ashwagandha improves the ability to enjoy the sexual experience but not necessarily the desire. This gives an indication that it was more likely to have created this effect via the acetylcholine actions rather than by influencing testosterone levels. Hormones such as Testosterone have a greater influence on the desire for sex (libido) and the nervous system and neurotransmitters have a greater effect on the actual actions associated with intercourse. Withania is an effective acetylcholine esterase inhibitor and preserves acetylcholine in nerve synapses.

Probiotic discussion and influence on body shape

Recent research into the wonderful world of gut flora is becoming increasingly exciting and important for our state of health. There is so much more than simple gut function and interaction with food. Probiotics are important factors controlling our growth and development from brain function, learning and behaviour, cravings and food choices and other aspects relating to the obesity epidemic.
