Zallouh (Ferulis harmonis), is a small shrub which grows in a small region in the Middle East. Like a number of plants, zallouh has been proclaimed an "herbal Viagra." This is the Viagra alternative in Syria.

Zallouh (Ferulis harmonis) is a small shrub with thin leaves and tiny white or yellow flowers. Also known as "shirsh Zallouh" the plant grows between 6000 and 10,000 feet around massive Mount Haramoun, which straddles the borders of Syria, Lebanon and Israel. In that region, the plant is profuse, with many thousands of tons of zallouh growing on Mount Haramoun.
Zallouh has a long tradition of use by men with erectile problems, and for men and women with low libido. But the root has also enjoyed even broader use for sexual enhancement among healthy men and women, to increase sexual frequency, and to increase pleasure. Thus zallouh has been used as a true aphrodisiac, an agent for boosting lustful urges in healthy individuals, and adding extra excitement to lovemaking.

Zallouh will rebuild sexual health. But the plant is also rich in antioxidants, and it helps to retard the aging process. If you will take zallouh every day, it will help to keep you strong and youthful.
Zallouh has also undergone scientific clinical study. The Lebanese government is keenly supportive of what it considers a national treasure. In Beirut, the Lebanese Urological Society has sponsored clinical trials which have carried this traditional root of antiquity into the medical present. To date over 7000 men have participated in this research.
In the various clinical studies on zallouh, men selected as candidates for trials have 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 1000 milligrams of freeze-dried zallouh root, 80% experienced improvement. On a scale of 1 – 5, the men went from an average score of 1.26 (virtually no erection) to an average of 3.11 (a firm erection).
To complete the data collection on the study, the researchers surveyed the sexual partners of the male subjects. Approximately 80% commented that their partners were significantly improved.
In the largest zallouh study, 4274 patients ages 18 – 87 participated. Of these, 2722 took zallouh root, between 2 – 8 grams daily in the form of tea.; At the end of the year, 2199 patients on zallouh had completed the study, with an efficacy rate nearing 86% for improved erectile function. These results show promise for large doses of zallouh taken over an extended period. Not all the studies were quite as impressive, depending on the dosage of zallouh given, and the duration of the study. The lowest efficacy rates in clinical trials hovered around 60%, which is still very good, compared with placebo groups at about 10%.

Phytochemical Constituents
Among its many compounds, zallouh root contains ferulic acid and feruloside, which dilate blood vessels and stimulate circulation. When zallouh is taken, an erection occurs as a result of increased blood flow to the fine vessels of the penis. Of course, as with any substance, zallouh is not a totally free ride. Those with hypertension, significant heart disease or diabetic neuropathy should not take zallouh root without the approval of a physician. Some individuals who take zallouh experience flushing and headaches as a result of the circulatory effects of the root.
For the most part, however, zallouh root and its various preparations appear safe and effective for a majority of users.
