This Stress Busting Tea Could Reduce Your Cancer Risk, Fight Inflammation and More

The World Health Organization tells us that cancer is the second leading cause of death on planet earth, taking 9.6 million lives in 2018 alone. With these skyrocketing rates of cancer, many are turning to natural cancer-fighting remedies to keep healthy. Soursop tea is just one example, but does it really pack the cancer-fighting punch that many claim? A closer look reveals that this is indeed a powerful elixir. 

What is soursop?

Native to the tropics of North and South America, soursop is a tree that is well known for its fruit and leaves. Also known as graviola (Annonaceous muricata L.), this Amazon fruit tree may also be called guanabana in some parts.

Described as a cross between a mango and a pineapple, the delicious fruit from this tree is often used in ice cream, custards, and drinks while its leaves hold powerful medicinal properties.

What is soursop tea?

The plant leaves have a long history of being used as an alternative treatment for cancer and can be enjoyed as a tea. Researchers from around the world have been studying the promoted cancer-fighting properties found in soursop tea for some time, and the results have been pretty amazing.

What research has uncovered about soursop tea and cancer

Published scientific studies show a very strong potential for the ability of soursop tea to fight cancer. Here is what you should know:

The leaves of the soursop tree contain acetogenins, which fight cancer cells while leaving healthy cells alone. This is huge considering that conventional cancer treatments damage both cancer cells and healthy cells, putting tremendous strain on the body.

Here are some research results for the impact of soursop tea on specific types of cancer.

Colon cancer


  • The Asian Pacific Journal of Clinical Nutrition published a study in 2017 that included thirty patients with colorectal cancer. Patients had undergone tumor surgery and were given a placebo or soursop leaf extract. Results showed that the group that received the soursop had higher cytotoxicity in their cancer cells compared to the placebo group.


  • A 2015 study found that soursop leaves do have the potential to reduce the risk of colon cancer. This, they found, is due to a constituent called “annomuricin E.”
  • IN 2008, Toxicology Letters found that acetogenins isolated in soursop help to reduce colon crypts in rats by up to 50%.
  • In 2014, researchers released evidence that soursop leaves induced death in colon cancer cells in an in vitro setting.

Breast cancer

  • According to research published in Advances in Breast Cancer Research in 2014, a 66-year-old woman undergoing chemotherapy for breast cancer drank soursop tea. Her breast cancer was stabilized as a result.
  • Current Pharmaceutical Design reported in 2016 that leaf extracts from soursop were able to inhibit breast cancer cells up to 98% in laboratory settings.
  • BMC Complementary and Alternative Medicine reported in 2016 that soursop extracts from leaves could be a potential breast cancer treatment. Extracts were found to induce death in breast cancer cell lines.
  • The Journal of Ethnopharmacology published a study in 2011 that found that annonacin from soursop, led to cell death in estrogen receptor-alpha-related pathways of breast cancer cells in mice.

Prostate cancer

  • Research has found that the flavonoids and acetogenins in soursop may inhibit tumor growth in prostate cancer cells.
  • Scientists found that soursop leaves contain two constituents that have cytotoxic properties against prostate and pancreatic cancer cells.

Lung cancer
