Hypertension is a common lifestyle disorder with a very strong risk factor predilection for cardiovascular diseases. Several surveys in the last two decades have reported a prevalence of 6.1% to 36.35% in men and 2%-39.4% in women in urban areas, and from 3%-36% in men and 5.8%-37.2% in women in rural areas respectively .The prevalence of hypertension increases with age and it is estimated that starting from around 15% -20% in early age, it increases to 75% -80% in individuals above 70 years of age.

     In conventional medicine, certain classes of antihypertensive drugs such as diuretics, calcium channel blockers, ACE inhibitors and Beta-blockers etc are in vogue with certain degree of adverse effects including hyperkalaemia, metabolic acidosis, gynaecomastia, hypotension etc with some contraindications such as COPD, gout, heart block and renal artery stenosis. Furthermore, some of these medicines are much costly. Hence, the alternative therapies should be explored for the better and safe management of hypertension.

     In Unani system of medicine, hypertension has been described under the term Imtila and  various single and compound Unani drugs have been mentioned for its management such as Tukhm-i Kahu, Asrol,  Parsiaoshan, Dawa-us-Shifa, Habb-e-Mudir, Sharbat-e-Buzoori, etc..

     Tukhm-i Kahu is one among the best Mudir (Diuretic) Advia. Besides of being Mudir, it also reduces the Hiddat of Khun leading to reduction in Imtila and signs and symptoms associated with hypertension.

Keeping the above facts in view, it has been planned to conduct a clinical trial entitled “A Clinical Study to Evaluate the Efficacy and Safety of Tukhm-i Kahu in the Management of Zaghá¹­ al-Dam Qawi Lazimi (Essential Hypertension)”.
