Soursop, also known as graviola (Annona muricata), is a tropical fruit tree native to the Americas. Various parts of the plant, including the fruit, leaves, and bark, have been traditionally used for their purported medicinal properties. It is commonly consumed as a fruit, juice, or in the form of teas and supplements made from its leaves. In traditional practices, it has been used for ailments ranging from infections to inflammation.
Quick answer
What it is: Soursop, also known as graviola (Annona muricata), is a tropical fruit tree native to the Americas.
The current evidence for soursop is largely based on preclinical in vitro and in vivo studies, primarily focusing on its potential anticancer effects. There is a lack of human clinical trials to support these uses, which contributes to its current low evidence grade.

Community signal breakdown
Where this remedy is being discussed across the web and community.
A classical ketogenic diet typically provides ~70–80% of calories from fat, ~15–20% from protein, and only ~5–10% (often 20–50 g/day) from carbohydrates. The metabolic shift to ketosis lowers blood glucose and insulin, raises ketone bodies (beta-hydroxybutyrate, acetoacetate), and is being studied for neurological and metabolic conditions. Variants include the Modified Atkins Diet (MAD), Medium-Chain Triglyceride (MCT) ketogenic diet, and the Low Glycemic Index Treatment (LGIT).
Foods to emphasize
Fatty fish (salmon, sardines, mackerel)
Pasture-raised eggs
Avocado and olives
Extra-virgin olive oil, coconut oil, MCT oil
Grass-fed meat and poultry
Full-fat dairy (butter, ghee, hard cheeses)
Nuts and seeds (macadamia, pecan, walnut, chia, flax)
Low-carb leafy greens and cruciferous vegetables
Bone broth and electrolyte-rich foods
Foods to avoid
Sugar and sweetened beverages
Grains and starches (bread, pasta, rice, cereal)
Most fruit (except small portions of berries)
Legumes and beans
Starchy vegetables (potatoes, corn, peas)
Low-fat or sweetened dairy
Vegetable seed oils (soybean, corn, sunflower) in excess
Most processed and packaged foods
Key principles
Carbohydrate intake usually 20–50 g net carbs per day
Adequate protein (~1.2–1.7 g/kg) — not high-protein
Most calories from whole-food fats
Track electrolytes (sodium, potassium, magnesium) to prevent "keto flu"
Best initiated with clinician guidance if on medications for diabetes, blood pressure, or seizures
Typical duration: Often 3–6 months minimum to assess response; medically supervised protocols (e.g. for epilepsy) may be maintained for years.
Why it may help
Cancer (Adjunctive Support): Investigated as an adjunctive metabolic therapy alongside standard oncology care — most evidence is preclinical or early-phase, with some glioma and glioblastoma trials. Should only be used under oncology and dietitian supervision.
Ketogenic therapy is a medical intervention when used for seizure disorders or oncology — work with a clinician or registered dietitian experienced in ketogenic therapy. Not recommended in pregnancy, type 1 diabetes without supervision, pancreatitis, certain fatty-acid oxidation disorders, or active eating disorders.
Anti-Inflammatory Diet
A whole-foods pattern designed to lower chronic, low-grade inflammation by emphasizing omega-3s, polyphenols, fiber, and minimizing ultra-processed foods, sugar, and seed oils.
The anti-inflammatory diet is not a single protocol but a synthesis of the patterns most consistently linked to lower inflammatory markers (CRP, IL-6, TNF-alpha) in human studies — Mediterranean-style eating, oily fish, abundant polyphenols, and low intake of ultra-processed foods, refined sugar, industrial seed oils, and excessive alcohol.
Foods to emphasize
Fatty fish 2–3x/week (salmon, sardines, mackerel, herring)
Extra-virgin olive oil
Berries, cherries, and other deeply colored fruit
Dark leafy greens and cruciferous vegetables
Turmeric, ginger, and culinary herbs
Green tea
Nuts (especially walnuts) and seeds (flax, chia)
Legumes and whole grains
Dark chocolate (≥70% cocoa) in moderation
Foods to avoid
Sugar-sweetened beverages and refined sugar
Ultra-processed snacks and ready meals
Industrial seed oils used at high heat (soybean, corn, sunflower, cottonseed)
Processed and cured meats
Refined flour products
Excess alcohol
Key principles
Cook with olive oil, finish with extra-virgin olive oil
Aim for 25–35 g of fiber per day from whole foods
Eat the rainbow — color diversity ~ polyphenol diversity
Limit added sugar to <25 g/day
Typical duration: A long-term eating pattern.
Why it may help
Cancer (Adjunctive Support): Lower dietary inflammatory index scores are associated with reduced incidence of multiple cancers in large cohorts.
Safe and flexible. Can be combined with Mediterranean, vegetarian, or plant-forward patterns.
Vegan Diet
A fully plant-based eating pattern that excludes all animal products — meat, fish, dairy, eggs, and honey.
A whole-food vegan diet emphasizes vegetables, fruit, legumes, whole grains, nuts, and seeds. It has been associated with improvements in body weight, blood lipids, and glycemic control, and is being studied for autoimmune and inflammatory conditions. It requires deliberate planning for vitamin B12, vitamin D, omega-3 (EPA/DHA), iodine, iron, zinc, and (sometimes) calcium.
Nuts and seeds (especially walnuts, chia, flax, hemp)
Fortified plant milks and nutritional yeast
Algae-based EPA/DHA supplement
Vitamin B12 supplement (non-negotiable)
Foods to avoid
Refined grains and sugar as the bulk of meals
Heavily processed vegan junk foods
Coconut and palm oils in excess
Key principles
B12 supplementation is required, not optional
Include a reliable iodine source (iodized salt or seaweed in moderation)
Get vitamin D from sun and/or a supplement
Combine grains and legumes across the day for complete protein
Choose calcium-fortified plant milk if not eating leafy greens daily
Typical duration: A long-term eating pattern.
Why it may help
Cancer (Adjunctive Support): Vegan cohorts show some of the lowest incidence rates of cancer in observational data, particularly for hormone-related and GI cancers.
Vegan diets can be excellent or deficient — quality depends on planning. Pregnant, breastfeeding, and growing children on vegan diets should be followed by a registered dietitian.
Vegetarian Diet
A plant-based eating pattern that excludes meat, poultry, and fish but typically allows eggs and/or dairy.
Vegetarian diets range from lacto-ovo (includes eggs and dairy) to lacto (dairy only) and ovo (eggs only). Done well, they are associated with lower rates of cardiovascular disease, type 2 diabetes, and some cancers. Done poorly, they can be high in refined grains and low in key nutrients (B12, iron, omega-3s, zinc).
Foods to emphasize
Legumes (lentils, chickpeas, beans, tofu, tempeh)
Whole grains (oats, quinoa, brown rice, whole wheat)
Vegetables and fruit, daily and varied
Nuts and seeds (almonds, walnuts, chia, flax, hemp)
Plan for protein at every meal (legumes, tofu, tempeh, eggs, dairy)
Pair iron-rich plants with vitamin C to boost absorption
Plan a reliable B12 source — fortified foods or a supplement
Include omega-3 ALA from flax, chia, walnuts; consider an algae-based EPA/DHA supplement
Typical duration: A long-term eating pattern.
Why it may help
Cancer (Adjunctive Support): Long-term cohorts (Adventist Health Study, EPIC-Oxford) associate vegetarian patterns with lower incidence of several cancers, especially colorectal.
Nutritional adequacy depends on planning, not just food choice. A registered dietitian can help avoid common gaps.
Linked nutrient deficiencies
Vitamin and mineral deficiencies commonly associated with the conditions this remedy may support.
Vitamin D
Fat-soluble vitamin
Hormone-like vitamin central to immune function, mood, bone, and thyroid health.
Low vitamin D status is one of the most widespread deficiencies globally and has been linked to autoimmune disease activity (Hashimoto's, MS), mood disorders, recurrent infections, and poor skin barrier function.
Common symptoms
Fatigue
Low mood
Frequent infections
Bone or muscle aches
Hair thinning
Food sources
Fatty fish (salmon, sardines)
Egg yolks
Cod liver oil
UV-exposed mushrooms
Fortified dairy
Lab markers to discuss
25-hydroxyvitamin D (target 40–60 ng/mL per most functional ranges)
Reference intake: Adults 600–800 IU/day RDA; functional medicine often targets 2,000–5,000 IU/day with monitoring.
Supplementation notes: Take with a fat-containing meal. Pair with vitamin K2 (MK-7) when supplementing higher doses long-term.
Why it matters here
Cancer (Adjunctive Support): Observational and some interventional data link adequate vitamin D to improved outcomes in several cancers.
Omega-3 Fatty Acids (EPA/DHA)
Essential fatty acid
Anti-inflammatory lipids critical for brain, joint, and skin health.
Selenium reduces TPO antibodies in Hashimoto's and supports T4→T3 conversion. Deficiency is implicated in thyroid autoimmunity and viral susceptibility.
Soursop appears to exert its effects primarily through compounds called annonaceous acetogenins, which may interfere with cellular energy production and proliferation in various cell types.
How it works in more detail
In preclinical studies, particularly in vitro, annonaceous acetogenins have been observed to inhibit mitochondrial complex I, a key enzyme in the electron transport chain, within cancer cells. This inhibition can disrupt ATP production, potentially leading to cell cycle arrest and apoptosis. Other mechanisms suggested by in vitro research include anti-inflammatory and antimicrobial activities, though these are less studied in the context of human health.
How to use
Always consult a qualified clinician.
Editorial guidance
Suggested dosage
500–2000 mg/day fruit extract (short-term use only; consult a practitioner).
Research dosage range
No established human research dose
Typical onset
Due to a lack of human clinical studies, the typical onset of effects for soursop is not well-documented. Traditional uses often imply consistent, long-term consumption rather than acute effects.
When considering soursop products, look for supplements made from organically grown leaves or fruit to minimize pesticide exposure. Products should ideally provide information on the part of the plant used and any standardization of active compounds, though standardization for annonaceous acetogenins is not common. Third-party testing for purity and contaminants is advisable.
