Seaweeds May Help Manage Hypertension, Finds Study


Modern lifestyle comes with vibrant and tiresome regular routines. Amid all the going for walks towards time and looking after societal and circle of relatives duties, our health takes a backseat. Of all life-related illnesses, hypertension, melancholy, and tension have become increasingly commonplace due to their disturbing existence. Hypertension is suggested by high blood pressure, where blood applies an extra force on the partitions of the blood vessels. The disorder of blood vessels poses the danger of laying low with coronary heart ailments like coronary heart assault or heart stroke. Hypertension may be controlled by making lifestyle adjustments and amending one’s diet, but it’s far as tough substitute trouble to put off speed completely.

Thankfully, a current scientific leap forward has included a probable answer for fighting hypertension. The town-headquartered Central Marine Fisheries Research Institute (CMFRI) observed that seaweeds might be used to make a nutraceutical product – Cadalmin Antihypertensive extract (Cadalmin AHe) – that can be administered orally to manage high blood pressure. The drug was released by the Indian Council of Agricultural Research (ICAR).

Kajal Chakraborty, the Senior Scientist at the CMFRI, discovered, “The extract consists of a hundred in step with cent natural marine bioactive substances from selected seaweeds with the aid of patented technology, and might be made to be had in 400 mg tablets. This nutraceutical has no facet outcomes as mounted via distinct pre-scientific trials.”


Seaweed is a form of algae. This is mainly found in the Indian coastal waters. It is also called sea vegetabless and is normally eaten in Asian international locations in sushi, soup, and salad. It is said to contain wonderful medicinal and health-giving residences.

ICAR-CMFRI Director A. Gopalakrishnan stated, “The institute is growing fitness products from the underutilized seaweeds. Efforts are on standardizing and promoting seaweed farming along the Indian coasts as a livelihood option for coastal communities. This is expected to atone for the dip in earnings for the fishermen at some stage in lean seasons.”

What is hypertension?

Hypertension or high blood pressure is the increased rise in the arteries. It increases the risk of associated cardiovascular (heart) diseases such as stroke, myocardial infarction, failure of kidneys or heart, and other vascular complications.

What are the blood pressure ranges?

According to current guidelines, the normal blood pressure is < 130 and < 85. In hypertension, the treatment is influenced by other risk factors, such as pre-existing heart diseases and diabetes.

A list of hypertension ranges from normal to risk levels are given in the table below;

Systolic (mm Hg)
Diastolic (mm Hg)
High normal
Mild hypertension
Moderate hypertension
Severe hypertension
Isolated systolic hypertension

What is blood pressure?

The heart supplies oxygenated or pure blood to all parts of the body through the help of vessels called arteries. The force with which the blood pushes against the artery’s walls is known as BP. The heart pumps blood into the arteries as it is beating. When filled with blood, the pressure exerted on the artery walls is known as systolic pressure and is 120 normally. The heart relaxes between the beats or pumping the blood into the arteries. This is when the pressure falls, known as diastolic pressure. The diastolic pressure is normally 80.

What causes hypertension?

A majority (about 95%) of patients have essential hypertension or primary hypertension. The main reasons behind this hypertension are known to be;
