Some Traditional Treatments With Soursop

The fruit seeds are used to control vomiting.

The leaves help in treating skin affections when applied as a poultice.

The fruit pulp helps to heal wounds faster when applied on them.

The root bark is used as an antidote for poisoning.

A decoction or tea made of leaves is used to get rid of head lice and bed bugs.

In the Caribbean, soursop leaves are commonly used as a remedy for insomnia by brewing them to make a beverage. In fact, the leaves used in a pillowcase have been found to promote sleep.


Health Benefits Of Soursop

In lab experiments soursop has been found to have the following properties :

  • Antileishmanial - Leishmaniasis is a disease which causes skin ulcers and affects orans like spleen and liver as well and is caused by the protozoa Leishmania which is spread by some types of sandflies.
  • Cytotoxic - Causes death of certain types of cells since it is toxic to those cells. This property could be used to target specific types of cells like cancer cells.
  • Antinociceptive - Reduces sensitivity to painful stimuli.
  • Antidiabetic.
  • Anticancer.

Research has shown that soursop is able to kill almost 12 types of cancer cells including those of the colon, breast, lung, pancreas and the prostate.

It has been found, in vito studies, that the compound, cis annonacin in soursop, seeds is up to 10000 times more effective in reducing growth of colon cancer cells than the commonly used chemotherapeutic drug Adriamycin.

More importantly, this compound kills selectively the cancer cells while leaving the healthy cells unharmed.

Human studies though, have not been done on the anti cancer effects of soursop.

The bottom line then being that though soursop holds promise as an anti cancer agent, in the absence of human studies and the possibility of side effects soursop extracts need to be used with caution.

These extracts should not be taken as a standalone anticancer treatment.

Among the other properties of soursop that have been established by research are:

Anticonvulsant, antifungal, antimutagenic, antispasmodic, antioxidant, sedative, uterine stimulant and vasodilator.


Some Side Effects And Precautions With Soursop

  1. Soursop or graviola may cause movement disorders/symptoms similar to that encountered in Parkinson's disease and thus worsen these symptoms.
  2. Web MD lists graviola as unsafe since it can kill nerve cells in the brain as well as in the body.
  3. Pregnant women and those breastfeeding should avoid it.
  4. Graviola lowers BP. Hence, those with low BP or on blood pressure lowering medications should keep this fact in mind.
  5. Large doses of soursop may cause nausea and vomiting.,
  6. Avoid taking soursop with Coenzyme Q10 or other supplements that increase ATP.

We have guanabana here in Peru. I've heard the claims about cancer and I suppose if I had cancer I would probably try it, but the contraindications are too risky for a healthy person, in my opinion. Thank you for sharing both sides of the story.
