Avena Sativa is wild oats which is harvested in the milky stage. References to the sexually stimulating effects of wild oats have been found up to 200 years ago in the German Pharmacopoeia.
Avena Sativa works by freeing up testosterone, the hormone responsible for sex drive in both males and females. When testosterone is freed from its binding receptors, nature takes it course by stimulating sexual interest in both men and women.
In 1986, the Institute For Advanced Study of Human Sexuality, a graduate school specializing in Sexology conducted a pilot study of Avena Sativa. The volunteers in the study expressed interest in improving their sexual response. Their dysfunction/dissatisfaction ranged from male impotence and female lack of desire to inability to respond sexually. The volunteers, ages 22-64, consisted of 20 men and 20 women who were give a 300 mg capsule of Avena Sative extract; which they took three days a week for six weeks. Men experienced a 22% increase in genital sensation and women experienced a 15% increase in genital sensation. Men experienced a 36% increase in the frequency of orgasms and women experienced a 29% increase in the frequency of orgasms.
Megabust uses the 10:1 oatstraw extract in its formula which translates into more mgs per week then that used in the above study.
