Is Zallouh For You?
By Chris Kilham
This ancient remedy helps to boost sexual performance.
These days, a number of herbal products are purported to boost libido and sexual function. Yet only a few demonstrate a long history of safe usage and are validated by science. One such herb is a plant employed in the Middle East since Biblical times: zallouh (Ferulis harmonis).

Zallouh (pronounced zalloo) grows on massive Mount Haramoun, which straddles the borders of Syria, Lebanon and Israel. The traditional use of zallouh has been to treat men with erectile problems, and to boost the libido of both men and women. But the root has enjoyed even broader use among healthy men and women as a way to increase sexual frequency and pleasure.

While many reputed aphrodisiacs are the subjects of folklore alone, zallouh has been investigated extensively in clinical trials. In a crowded field of plants and potions jockeying for position as the natural alternative to Viagra, zallouh stands out, with more clinical validation than any other.

Each plant needs a champion in order to become the object of credible and expensive clinical research. In the case of zallouh, that champion is the Lebanese Urological Society in Beirut, which has sponsored a series of human studies conducted on a large scale. More than 7,000 men have participated in this research.

In the clinical studies on zallouh, men selected as candidates for trials have uniformly experienced some measure of erectile dysfunction. In one six-month study of 315 men with a mean age of 55, among the 159 who took either 500 or 1,000 mg of freeze-dried zallouh root, 80% experienced improvement. On a scale of 1 to 5, the men went from an average score of 1.26 (virtually no erection) to an average of 3.11 (a firm erection).

In the largest zallouh study, 4,274 patients ages 18 to 87 participated. Of these, 2,722 took between 2 and 8 gm of zallouh root daily in the form of tea. At the end of the year, 2,199 patients on zallouh had completed the study, with an efficacy rate for improved erectile function of nearly 86%. These results are rather spectacular and show the value of zallouh when taken in large doses over an extended period. The lowest efficacy rates in the clinical trials hovered around 60%, compared with the placebo groups at about 10%.

Zallouh root contains ferulic acid and feruloside, which dilate blood vessels and stimulate circulation. When zallouh is consumed, an erection occurs as a result of increased blood flow to the fine vessels of the penis. Men with hypertension, significant heart disease or diabetic neuropathy should not take zallouh root without the approval of a physician.

For the most part, zallouh root appears to be safe and effective for the majority of users. A few studies show that zallouh can work in as little as 30 minutes after ingestion. For those who seek an herbal aphrodisiac that delivers real results, approximately 250 to 1,000 mg of zallouh root per day just may produce the firm erection they seek .

What to Look For

Zallouh root in freeze-dried form is available in tablets and capsules. The daily recommended dosage ranges from about 250 to 1,000 mg per day. There are no known drug interactions, and the majority of users tolerate it extremely well, noticing significant improvement in both libido and sexual function. Three products that contain efficacious amounts of zallouh are Zallnex, Zamoreve and Natural Passion for Women. All can be found in health food stores. Persons with pre-existing medical conditions should consult with a physician before taking zallough.
