Have a headache? Try soursop. Joint pain? Soursop. Infection? Soupsop. Parasite? Yep, you guessed it: Soursop might help.

Soursop (Annona muricata) also goes by the names guayabano, graviola, custard apple, guanabana, sirsak, and paw-paw. It looks like a prickly avocado and grows in tropical and subtropical climates. While the fruit has a creamy texture and is widely considered delicious, the seeds and leaves are also often used for medicinal purposes. Scientific research suggests that soursop may have more than a dozen overall health benefits thanks to its robust nutrient profile. 

13 health benefits of soursop

In one piece of soursop, you get the following recommended daily value of these macronutrients, vitamins, and minerals:

• 20 g of fiber (~70-90% RDV)
• 128 mg of vitamin C (more than 100% RDV)
• 87 mg of calcium (~10% RDV)
• 131 mg of magnesium (~25% RDV)
• More than 1,700 milligrams of potassium (~33% RDV)
• 87.5 mcg of folate (~20% RDV)

This breakdown is important because these macro- and micronutrients are linked to the following benefits: 

1. Provides antioxidants

Eating a diet rich in antioxidants may help protect you against disease. Antioxidants are substances that fight free radicals, which are known for damaging cells. Research notes that free radicals can lead to Alzheimer’s, cancer, and heart disease. 

Soursop fruit and leaf extracts have antioxidant properties because they contain vitamin C, flavonoids, acetogenins, tannins, phytosterols, and phenolic compounds. Studies suggest that the antioxidant content of each serving depends on the extraction method used; an extract made with a mixture of water and alcohol was found to be a safe and efficient source of antioxidants.

2. Boosts immunity

If you eat an entire piece of soursop fruit, you stand to get roughly 120 milligrams of vitamin C. 

“Soursop is rich in antioxidants like vitamin C, which can help support your immune system,” explains Ashley Kitchens, RDN, registered dietitian and owner of Plant Centered Nutrition in Durham, North Carolina. Vitamin C boosts your body’s natural defenses by protecting cells against free radical damage.

3. Fights bacteria

Western medicine typically treats bacterial infections with antibiotics. Those types of drugs may come with side effects, prompting many to seek natural alternatives, like soursop.

Researchers evaluated soursop’s antibacterial properties through an in vitro study (a study conducted in a non-living environment, such as a test tube). They tested soursop leaf extracts at varying concentrations and found them highly effective against certain bacterial strains, including major players such as Staphylococcus aureus, Vibrio cholerae, E. coli, and Salmonella. However, soursop is not an alternative to antibiotics prescribed by your provider. More research is needed to understand the connection between soursop and bacterial infections.

4. May treat or prevent ulcers

Ulcers are sores that often appear in the digestive tract, causing pain and bloating. Antibiotics and antacids are common treatments. 

There is limited evidence of using soursop to mitigate or treat ulcers in humans; however, there are several promising studies that involved testing on animals. In a study on mice, researchers found that soursop extract resulted in “significant anti-ulcer activity.” Research is limited, and more studies are needed to establish the benefits for humans.

5. Reduces inflammation

Inflammation in the body can cause all types of annoyances: joint pain, fatigue, and even digestive issues. There are natural and medicinal solutions available, with soursop emerging as a potential contender. 

In a study conducted on rodents, researchers found soursop extract has anti-inflammatory effects. Soursop helps fight free radicals that cause oxidative stress in your body, thereby reducing inflammation. Researchers concluded that the extract they used lessened inflammation and helped relieve pain. 

6. Shows anti-parasitic activity

It is well documented that soursop is used in various parts of the world to treat parasites. Several in vitro studies have put the plant’s leaf extracts and seeds to the test, finding promising antiparasitic results. In a controlled study performed on sheep, the leaf extract brought as high as 89% toxicity against gastrointestinal parasites. 

7. May help manage blood pressure

If you have high blood pressure, consuming soursop could potentially complement any treatments you’re on. A controlled trial of 143 people found that those who consumed 100 grams of soursop juice twice a day for three months had significantly lower average systolic blood pressure than the control group, who were not treated.

8. May help relieve headaches

Could soursop treat headaches? Maybe so. The leaves of the plant have been used across the world to treat headaches when steeped in tea. This is due to the plant’s known ability to reduce inflammation. A word of caution, though, is that there aren’t any studies to support soursop’s direct effect on headaches, and current evidence appears to be anecdotal.

9. May lower blood sugar levels

A number of in vitro studies suggest that soursop fruit extracts may help people manage blood sugar levels. This is because the extracts inhibit α-amylase and α-glucosidase, which influence your blood glucose levels. It’s also thought that soursop may slow the breakdown of carbohydrates, reducing the amount of glucose your body absorbs.

10. Can help arthritis symptoms

Because soursop has anti-inflammatory properties, it may be used to help relieve symptoms of arthritis. In one study, researchers pretreated rats with soursop fruit extract and then injected them with carrageenan to elicit edema (swelling). They found that soursop significantly inhibited swelling and noted that the results were on par with the “most clinically effective anti-inflammatory agents.”

11. Boosts digestive health

The dietary fiber content in soursop, roughly 20 grams per serving, may be one key to unlocking your digestive health. “Fiber can help improve digestion and gut health,” says Kitchens. She explains that fiber promotes regularity and feeds the good bacteria that live in your gut.

12. Shows potential anti-cancer activity

An extensive scientific review notes that graviola (another name for soursop) is a popular treatment for cancer in some countries. Extracts from the plant were found to offer protection against malignancies, including colon, breast, and prostate cancers. 

This isn’t to suggest that you should avoid medicine and turn to soursop. The review does note that “many questions still need to be addressed” when it comes to using soursop to treat cancer. 

 “Lab studies (in vitro) show there may be some antimicrobial and anti-cancer properties, but the data is inconclusive in humans,” says Erika Gray, Pharm.D., founder and chief medical officer at ToolBox Genomics.com. 

13. May help weight loss efforts

A study on the use of graviola (soursop) leaf tea in mice found that the plant helps reduce body weight and “attenuated the accumulation of lipids” (a fancy way of saying it prevented body fat). As a result of reduced body weight and body fat, soursop tea was also potentially linked to a reduction in cardiovascular risks associated with cholesterol and triglycerides.

Important considerations and potential downsides

There are a number of claims about soursop’s health benefits, such as improving sleep, but we couldn’t find any science-backed evidence. Additionally, while soursop has potential effects on inflammation, blood pressure, and even cancer cells, the plant has not been recommended by health professionals as a “miracle cure” for any of these or the other issues outlined here.

Soursop can be a beneficial addition to your diet, though it may not be safe for everyone. There are several groups of people who should avoid the fruit or consume it with caution.

“The main group at risk is those with neurodegenerative diseases,” says Dr. Gray. “People with a family history of neurodegenerative disorders should avoid eating soursop.”

Soursop contains annonacin, which is a mitochondrial toxin, she explains. Chronic consumption has been linked to neurodegenerative illnesses like Parkinson’s disease. It could also lead to side effects like low blood pressure and liver damage.

Dr. Gray also suggests the following people should avoid or use soursop with caution:

• Pregnant and breastfeeding people should avoid soursop, as there is a lack of human safety data
• People on diabetic and blood pressure medications should be cautious of signs of low blood pressure and low blood sugar
• People on anticoagulants, as soursop could act as a natural blood thinner
• People with kidney issues, as soursop in high doses could cause damage to those organs

Lastly, Dr. Erika Gray advises that soursop should not be taken daily or long-term. She warns that people should avoid consuming extracts or seeds because of the higher concentration of annonacin.

How to incorporate soursop into your diet

Kitchens says she has consumed soursop many times while traveling and finds it delicious. She notes that a typical serving size is 1 cup of chopped, fresh fruit to get the health benefits. She also recommends eating it as part of a balanced diet that includes a variety of fruits and vegetables. 

“My favorite way to enjoy soursop is by simply cutting the fresh fruit in half and scooping out the white pulp while discarding the seeds,” she says. 

Kitchens suggests the following additional ways to add soursop to your diet:

• Blend it into smoothies
• Add it to yogurt or granola
• Incorporate it into a fruit salad
• Juice it and drink it
• Juice it and turn it into a frozen dessert like ice cream

Health experts advise against consuming soursop daily, as it can become toxic at certain doses, especially when consumed as extracts. The time of day you choose to consume soursop depends on your goals. Taking it on an empty stomach can promote better absorption of vitamins and minerals; if you prefer to drink it as a tea, you may prefer to take it at night as part of a soothing evening ritual.

Is soursop the next superfood? The verdict

Soursop may well be considered a “superfood” thanks to its potential health benefits. Most studies on the plant have been either in vitro or on animals, though many results are promising for humans as well. If you have pre-existing conditions, make sure to speak with your healthcare provider before incorporating soursop into your diet.
