ANTI INFLAMMATORY ACTIVITY OF SOURSOP

 

Due to significant side effects of steroid and non steroidal Anti-inflammatory Drugs (NSAID), there is an increasing interest in herbal remedies that have been in use for many years to minimize pain and inflammation. The great number of natural compounds work similarly to that of the NSAIDs.

The mechanism of antinociception (reduced sensitivity to pain) has been shown to inhibit cyclooxygenase (COX) and lipoxygenases (LOX) through inflammatory mediators such as flavonoids present in the plant extract.

The anti-inflammatory effects of Annona muricata are thus demonstrated to occur through suppression of inflammatory mediators.

A. muricata produced dose-dependent and significant results, which were comparatively similar to the inhibition of inflammatory pain produced by morphine (96.08%) standard reference drug. The effect of the extract in this phase suggests that it may have an anti-inflammatory property.

In conclusion, findings from the results of the studies showed that A. muricata possesses analgesic and anti-inflammatory activities in various models. The analgesic effect involves interaction with peripheral mechanisms and opioid system, whereas the anti-inflammatory property involves inhibition of COX activity and nitric oxide generation. Hence justify its use in traditional African medicine in the management of painful conditions and inflammatory disorders.

PHYTOCHEMISTRY OF SOURSOP AND ITS MEDICINAL USES

  The phytochemistry of  Annona muricata  L. (Laxmanphal) There are sufficient reasons that Soursop is gaining its popularity in the Health Sector.

SOURSOP - AN EXCELLENT ANTIOXIDANT

What is Oxidation ? Oxidation is a chemical process where molecules lose electrons, often resulting in the formation of unstable Free Radicals. To get stabilized, these free radicals further snatch electrons from the nearby healthy cells, making them unstable. It's a chain reaction, making the cell and its ingredients unstable, resulting in cell damage.  What are Antioxidants ? Antioxidants are the substances that donate electrons to Free Radicals, making them stable, preventing probable cell damage.  Oxidative Stress Condition  is the tug of war between oxidation-causing agents and antioxidants for electrons . This is a condition when there is an imbalance between the amount of  Reactive Oxygen Species (ROS)  and  Antioxidants . Increasing scientific evidence is concerning, as it suggests that ROS and Oxidative Stress play crucial roles in developing chronic diseases like pathogenesis, such as Cancer, neurodegenerative diseases, and cardiovascular and...

SOURSOP IN CANCER ADJUVANT THERAPY

  Annonaceous Acetogenins are the most valuable phytochemicals present in Soursop/ Laxmanphal, scientifically known as Annona muricata . Annonaceous acetogenins typically are derivatives of long chain fatty acids that are selectively toxic to Cancer cells, including multidrug resistant Cancer cells. Scientific research carried out by Hadisaputri et al (2021) conclude that Annona muricata leaf extract is responsible for the induction of apoptosis of breast cancer cells. This apoptosis is majorly due to reduction in the integrity of mitochondrial cells. Cancer cells may develop Multi Drug Resistance (MDR), a phenomenon in which Cancer cells develops resistivity against the the specific drug being used in the Cancer treatment. Acetogenins (ACG) in Soursop are found to be cytotoxic to these Drug Resistant Cancer cells. As a result, these Cancer cells undergo death and decay, preventing the spread of Cancer to other parts of body (Metastasis). Annonaceous acetogenins induce cy...
