In Africa a lot of illnesses are treated with herbs and fruits believed to cure them. While some may be true, others are not.

A Facebook user posted that goron tula could be used to cure infection, ulcer, diabetes, cough, infertility and other illnesses.

This multipurpose cure seemed too good to be true, prompting us to look into the claim.

But first, we looked at what an infection is. An infection occurs when a microorganism enters a person’s body and causes harm.

The microorganism uses that person’s body to sustain itself, reproduce, and colonize. These infectious microscopic organisms are known as pathogens; they can multiply quickly. Examples of pathogens include bacteria,viruses, and fungi.

Diabetes on the other hand is a “chronic disease that occurs either when the pancreas does not produce enough insulin or when the body cannot effectively use the insulin it produces. Insulin is a hormone that regulates blood sugar.


Dubawa researched this Snot apple and it’s properties to find out why it is believed to be a miracle fruit.

Snot apple (goron tula)

Snot apple (goron tula), although relatively unknown by many, is considered a ‘miracle fruit’ by those who know it for its many health benefits.

It is known by different names; tree hibiscus, Azanza, snot apple in English language, goron tula in Hausa etc. It is found in the northern part of Nigeria.

It is sweet and chewy as well; hence it is also called “African Chewing Gum” fruit.”

The fruit is widely cultivated in Gombe State and Adamawa State in Nigeria. Its botanical name is azanza garckeana.

Properties of snot apple (goron tula)

Phytochemical composition of Azanza garckeana (goron tula) shows that it comprises Tannin 0.22%,Saponin 1.72%, Alkaloids 3.7%, Flavonoids 1.0%, Phenol 2.60%, Cyanogenic glucosides 0.33ug/g and Carotenoids 3.40%.

These nutrient are important due to their medicinal,nutritional, and genetic functions and have been linked to be involved with anti bacterial and antiviral activities.

Dubawa also went ahead to find studies related to this fruit and its potency.

One study titled- effects of chemicals extracted from  Azanza garckeana  Mansonone E, C, G and H displayed antifungal activity against  P. parasitica,  with Mansonone E  showing  the highest activity. Also, the study suggests potential Mansonone E as a new natural pesticide  for agricultural plant pathogen management. 

The  plant  has  antifertility/contraceptive properties: Antioxidant properties, Antiparasitic  properties,  Antivirus  properties, Antimicrobial  properties,  Plasma cholesterol  reduction”.

The study noted that different  pharmacological activities of the chemicals   from  the  plant  justify  the  use  of  snot apple (goron tula) to treat  various diseases  and health conditions, especially sexually related problems, as exposed by different researchers. It also added that the use of the plant for further research may help to lead even to new drug discovery.

Expert opinion

Dubawa spoke to doctor Jemimah Abner, who said fruits are very helpful in treating illnesses. 

“There are a lot of publications that give us a picture of some of the chemical substances available in the snot apple. It appears to have good medicinal functions that include antibacterial, antifungal, antihyperglycemic, antimalarial, antioxidant and iron absorption activities.

Abner added that,” the fruit has been recommended by nutritionists because of their health benefits as they are considered to be responsible for positive health outcomes.”

Generally, intake of natural foods and fruits is strongly encouraged compared to intake of some drugs.

Even drugs cannot substitute for endowed foods and fruits, she said. 

Abner further added, “However, deeper research would need to be conducted. There should be experimental animal studies, randomized clinical trials, and target-organ toxicity studies involving snot apple  and its derivatives. It will be important to investigate the isolation of the bioactive compounds, mechanisms of action and safety of such bioactive compounds.”

Speaking to Dr Jerry Agim, a gynecologist, he said “One fruit cannot possibly help with all the diseases and illnesses named here. Certainly not. But research should be carried out.”


Although the plant has been said to have medicinal functions, the claim calls for further research to be able to ascertain all the illnesses it works for.
