Bitter leaf benefits

The many bioactive components of bitter leaf has conferred strong healing capacities on the plant towards several ailments. Some of these health benefits are going to be discuss in this article. So let’s quickly dive into the sea of bitter leaf world.

Bitter leaf possess anti inflammatory Bioactive Agents

Inflammation, as you know, is a common tissue phenomenon which occurs when the tissue is exposed to trauma or injury. This inflammatory response to trauma and injury can be attenuated if you drink a cup of bitter leaves juices. This is because bitter leaf juice possesses saponins, tannins, alkaloids, flavonoids, and glycosides, all of which suppress inflammatory responses.

Another anti inflammatory agent is Zinc element, which the juice possesses. Zinc is an essential element which regulates most of the enzymes that are involved in inflammations. The anti-inflammatory activity of Verononia amygdalina was comparable in magnitude to dexamethasone, in a research conducted by Biressaw and Birhanu.

These means that bitter leaves juice will be effective for the treatment of such diseases like joint pains, rheumatoid arthritis, and headache.

Possess antipyretic and analgesic property.

Both the brewer’s yeast and lipopolysaccharides induce pyrexia in animals and human body. Such induction activates the arachidonic acid pathway and has been associated with elevated prostaglandin E2 (PGE2) level in the hypothalamus. But the antipyretic agents present in bitter leaf juice have been to antagonize the PGE2 elevation by inhibiting the activity ofcyclo-oxygenase thereby suppressing pyrexia.

Bitter leaves possess antimalaria properties

Malaria is the commonest cause of deaths among subsaharan African nations. This is due to the incessant infestation of mosquitoes owing to the many presence of bushes and stagnant waters that are littered everywhere.

According to a research finding, malaria is one of the most important tropical diseases and the greatest cause of hospitalization and death among children of age 6 months to 5 years.

Initially, chloroquine was readily used to treat malaria but the rate at which plasmodium falciparum has developed resistance to chloroquine and other synthetic antimalaria drugs has prompted the search for a more effective antimalaria compound.

It is thanks to nature for the gift of herbs such as bitter leaves tree. Both the aqueous and ethanolic extract of both the stem bark and leaves of V. Amygdalina has shown strong promise for treating malaria infection.

This antimalaria activity of the lea and stem back is associated with some bitter Sesquiterpenes lactones such as, Vernolide,Vernodalin, hydroxy Vernolides, and the steroid related compounds, Vernoniosid B1 and Vernonoid B1 present in the bitter leaf. They possess anti-plasmodium activity especially against plasmodium falciparum.

Bitter Leaf Juice Possesses Antioxidants

As a source of antioxidants, bitter leaf juice would replace the synthetic antioxidants such as butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA), which are suspected to be tumorigenic. More so is the research report by Igile et al, that luteolin is more potent as an antioxidant than BHT.

In another study conducted on the oxidative stress in diabetic rats, result showed that the aqueous extract of Verononia amygdalina decreased the levels of serum malondialdehyde, which is an indication of antioxidant property.

In yet another conducted by Owolabi et al, the plant ethanolic and aqueous extracts inhibited the bleaching of β-carotene, oxidation of linoleic acid and lipid peroxidation induced by Fe2+/ascorbate in rat liver microsomal preparations.
