How About Soursop (Graviola) Leaf Tea As A Preventive Measure for Coronaviruses & Pneumonia

What is graviola and how is it used?

Graviola, also known as soursop or Brazilian paw paw, it serves a dietary supplement used to treat many conditions.

Graviola is hailed as a wonder herb. It's popularity as a natural remedy for viruses, pain relief, and even some types of cancer is gaining ground. 

Potential health benefits

Research suggests that graviola has a number of health benefits:

1. It has antioxidant properties

Antioxidants keep cells healthy by hunting disease-causing free radicals in the body and destroying them.

According to a 2014 study, graviola extract has many compounds with antioxidant abilities.

These include:

  • tannins
  • saponins
  • phytosterols
  • flavonoids
  • anthraquinones

Antioxidants help people stay healthy overall. More research is needed to determine if graviola's antioxidants prevent specific diseases.

2. It has anti-inflammatory properties

According to a 2014 study on rodents, graviola has anti-inflammatory properties that may relieve pain. The study's researchers supported graviola's use as a folk remedy for pain and inflammatory conditions.

A 2010 rodent study found graviola blocked pain receptors and reduced inflammation in rats.

3. It may help lower blood sugar

The results of a 2008 rodent study suggest graviola may help people regulate their blood sugar if they have diabetes. The study found that graviola significantly reduced blood glucose levels in rats with diabetes.

In addition, despite the rats being fed less food and water, they didn't lose weight. Researchers believe this may be the result of better glucose control.

4. It may help lower blood pressure

Graviola is often used as a folk remedy to lower blood pressure. Uncontrolled high blood pressure may increase the risk of heart disease, diabetes, and stroke.

A 2012 study on rats found graviola helped reduce blood pressure without increasing heart rate. 

5. It may help prevent ulcers

Ulcers are painful sores that develop in the stomach lining, esophagus, or small intestine.

According to a 2014 study on rodents, graviola showed antiulcer abilities. It helped protect the stomach's mucous lining. It also helped prevent free radical damage to the digestive tract.

6. It may help treat herpes

Herpes is a viral infection caused by the herpes simplex virus. It may appear on the genitals or mouth.

Graviola is considered an alternative treatment for herpes, but the supporting evidence is still coming in. A 2012 study showed antiherpes activity with graviola in the laboratory.

According to a 1999 study, graviola extract may have antiviral effects against herpes simplex 2 virus (HSV-2). HSV-2 is responsible for most cases of genital herpes outbreaks. In vitro, graviola was toxic to HSV-2 cells. In vitro means outside a living body.

7. It may be anticancerous

There is some evidence graviola may battle some types of cancer. According to 2016 in vivo and in vitro research, graviola extract was toxic against some breast cancer cell lines. In vivo means inside a living body, the opposite of in vitro.

It also increased T cells. T cells are lymphocytes in the body that kill cancer cells and other damaged cells.

A 2012 in vivo and in vitro study found graviola may be beneficial against some pancreatic cancer cell lines by inhibiting cellular metabolism.

Still, researchers caution graviola alone is not enough to eradicate pancreatic tumors. It should not be used as a primary treatment. Studies are ongoing to evaluate the efficacy of graviola as an adjuvant therapy for pancreatic cancer.


Pneumonia is a lung inflammation caused by bacterial or viral infection, in which the air sacs fill with pus and may become solid.

Inflammation may affect both lungs (double pneumonia), one lung (single pneumonia), or certain lobes (lobar pneumonia).

Chronic Obstructive Pulmonary Disease (COPD)

***Progressive lung diseases include emplysema, chronic bronchitis, refractory (non-reversible) asthma and some forms of bronchiectasis.


  • Increase breathlessness
  • Frequent coughing (with or without sputum)
  • Wheezing
  • Tightnness in the chest

Most people have symptoms of COPD and do not know it.




Two other human coronaviruses, MERS-CoV and SARS-CoV have been known to frequently cause severe symptoms.

MERS symptoms usually include fever, cough and shortness of breath which often progress to pneumonia.

About 3 or 4 out of every 10 patients reported with MERS have died. MERS cases continue to occur, primarily in the Arabian Peninsula.

SARS symptoms often include fever, chills and body aches which usually progressed to pneumonia.

No human cases of SARS have been reported anywhere in the world since 2004.




Graviola also has a long history of medicinal use for treating inflammatory conditions, diabetes, hypertension, insomnia, parasitic infections, and cancer. All parts of the tree including the bark, leaves, fruits, and roots are used in herbal medicine.

Interest in graviola as a potential anticancer agent surged following the discovery of its cytotoxic property in a 1976 plant-screening program by the National Cancer Institute. Annonaceous acetogenins, extracted from different parts of the tree, were found to have cytotoxic effects. These observations have yet to be confirmed in clinical trials. Nevertheless, despite lack of substantial evidence, graviola is heavily promoted as a cancer-fighting herb.
