Coriander leaf benefits

Coriander has been used as a condiment (flavour enhancer) in a majority of foods. In addition, it has been seen that coriander use can also result in a number of health benefits. Uses of coriander to promote a better health has been discussed in this article. 

The entire plant body of coriander has a number of uses and benefits. However, the plant part which mostly comes of great use is the leaves of coriander. Let us explore the uses and health benefits of coriander leaves.

  • Coriander leaves for kidney
  • Coriander leaves for cholesterol
  • Coriander leaves for the liver
  • Coriander leaves for good memory
  • Coriander leaves for blood pressure
  • Coriander leaves as antioxidants

Coriander leaves for kidney

A host of minerals like potassium, calcium, iron, manganese, and magnesium are found in coriander. Vitamins essential for maintaining optimum health like Vitamin A, Vitamin C, Vitamin B and beta-carotene (a pigment responsible for Vitamin A formation) are found in the leaves of coriander. Coriander leaves act as a diuretic and help in the cleaning process of the kidneys by increasing the amount of urination and removing toxic waste from the body.

Coriander leaves for cholesterol

Bioactive compounds present in coriander act as powerful antioxidants. These compounds help in regularising cholesterol levels in the body. Upon regular coriander consumption, Low-Density Cholesterol (LDL) and Very-Low-Density Cholesterol (VLDL) has been found to be lesser in percentage in patients with cardiovascular diseases.

Coriander also helps in reducing cholesterol levels by reducing triglycerides in the blood and increasing the content of High-Density Cholesterol (HDL) also known as the good cholesterol. 

Coriander leaves for the liver

A vast majority of metabolic functions in the human body are performed by the liver. Coriandrum sativum being rich in antioxidants acts as a hepatoprotective (protects the liver) by increasing the activity of certain enzymes as catalase, glutathione peroxidase, and superoxide dismutase. These enzymes help in removing toxins such as hydroxyl radicals (damage-causing agents) by binding with them and improving the proper functioning capacity of the liver.

Coriander leaves for good memory

Extensive studies on coriander strongly suggest that this herb significantly helps in improving memory function.

The primary manner in which coriander helps in boosting memory function is by blocking the cholinesterase enzyme (an enzyme present in the central nervous system) which is responsible for the breakdown of acetylcholine, a neurotransmitter (helps in conducting nerve signals).

Acetylcholine is required for the activation of muscle cells in the body. Coriander lowers the levels of oxidative stress in the brain which blocks the activity of cholinesterase and promotes the build-up of acetylcholine. This, in turn, helps in improving the memory function. 

Coriander leaves for blood pressure

Salad prepared with coriander leaves has often been found to be very beneficial in patients suffering from hypertension.

Coriander is rich in calcium which upon interaction with acetylcholine is responsible for releasing blood tension.

Intake of coriander thus has the potential of reducing the blood pressure levels. This property of coriander helps in reducing the chances of occurrence of numerous cardiovascular (heart) conditions such as cardiac arrest and stroke.

Coriander leaves as antioxidants

The human body is continuously exposed to external toxins present in the surrounding environment.

In reaction to these toxins, the body produces free radicals that cause damage to the cells and in the long run gives rise to diseases such as heart diseases, diabetes and cancer as well.

Coriander is a good source of antioxidants. Extract prepared from the leaves of coriander can reduce oxidative stress via the action of a large number of antioxidants like glutathione and minimize the damage caused by the free radicals.

Neurodegenerative (degeneration of the nervous system) disorders like Alzheimer's could be prevented by administration of coriander in a dose-dependent manner. Deficiency of the neurotransmitter, acetylcholine leads to Alzheimer’s. Acetylcholine is also required for muscle movement function and its degradation can lead to conditions like paralysis. Coriander can prevent the disease by blocking the activity of the enzyme cholinesterase which is responsible for the breakdown of acetylcholine.

In the study, it was found that volatile oils from coriander, when given to patients with nervous system diseases, can also help to counteract anxiety and stress. This is mainly achieved due to a decrease in the glutathione levels which causes a rise in anti-oxidative activity of the brain cells, thus, reducing anxiety and related conditions.
