Chrysophyllum (Chrysophyllum albidum): Benefits, Dosage, Safety & Evidence

Questions fréquentes

How does Chrysophyllum albidum work in the body?

Chrysophyllum albidum contains bioactive compounds including tannins, saponins, flavonoids, and vitamin C that contribute to its medicinal effects. The tannins provide astringent properties useful for wound healing and digestive conditions, while flavonoids offer antioxidant and anti-inflammatory effects. Preliminary research (Evidence level C) suggests these compounds may help regulate blood glucose levels, supporting its traditional antidiabetic use. The plant's antimicrobial properties, attributed to saponins and flavonoids, contribute to its effectiveness against fever and infections.

Does African star apple interact with any medications?

Currently, there are no well-documented drug interactions for Chrysophyllum albidum. However, due to its potential blood glucose-lowering effects observed in preliminary research (Evidence level C), individuals taking diabetes medications such as metformin or insulin should monitor blood sugar levels closely when consuming this herb medicinally. The tannin content may reduce absorption of certain medications if taken simultaneously. Consult a healthcare provider before combining with prescription medications.

What is the recommended dosage for Chrysophyllum albidum bark?

The traditional adult dosage for Chrysophyllum albidum bark is 2-3 grams prepared as a decoction. To prepare, simmer the bark in water for 15-20 minutes, then strain before consuming. The ripe fruit can be eaten freely as a nutritious food. Dosage recommendations are based on traditional West African practice rather than standardized clinical trials (Evidence level C). Start with the lowest effective dose and consult a qualified herbalist for personalized guidance.

Is African star apple safe during pregnancy and breastfeeding?

Based on traditional use, Chrysophyllum albidum is considered safe during pregnancy when consumed as food. The ripe fruit is widely eaten as a nutritious delicacy in West Africa without reported adverse effects. However, medicinal preparations such as concentrated bark decoctions have not been specifically studied in pregnant populations. Pregnant women should avoid consuming unripe fruit, which may cause gastrointestinal upset. Consult a healthcare provider before using medicinal preparations during pregnancy. Evidence level: Traditional use.

What are the health benefits of African star apple?

Chrysophyllum albidum is used in West African traditional medicine for treating digestive conditions, fever, and wounds. The bark and leaves are prepared as decoctions, while the fruit is consumed as a nutritious food rich in vitamin C and calcium. Preliminary research (Evidence level C) suggests potential antidiabetic properties, supporting its traditional use for blood sugar management. The plant's antimicrobial and anti-inflammatory compounds contribute to wound healing applications. The fruit remains a popular delicacy in Nigeria.

What are the side effects of eating unripe African star apple?

The primary reported side effect of Chrysophyllum albidum is gastrointestinal upset, particularly when unripe fruit is consumed in excess. Unripe fruit contains higher concentrations of tannins and other compounds that can irritate the digestive tract. Ripe fruit and properly prepared bark decoctions at recommended doses rarely cause adverse effects. There are no known significant contraindications. Individuals with allergies to plants in the Sapotaceae family should exercise caution. Evidence level: Traditional use and preliminary research (C).

Résumé

Chrysophyllum albidum, known as the African star apple, is a tropical fruit tree indigenous to West and Central Africa with documented nutritional, antioxidant, and anti-inflammatory properties [PMID:41895927, PMID:36765149].

Contexte

Chrysophyllum albidum (Sapotaceae family) is a forest food tree species producing large berries of nutritional, sanitary, and commercial value in many African countries [PMID:36765149]. It is an underutilized tropical fruit indigenous to West and Central Africa [PMID:41895927].

Usages traditionnels

In African healing systems, the plant has various ethnobotanical uses [PMID:37806006]. The stem-bark is used in traditional medicine to treat infections and oxidative stress-related diseases [PMID:28487910], while the seed is used for malaria, yellow fever, stomach ache, and inflammatory disorders [PMID:42036000]. The fruit is used in folklore to manage diabetes [PMID:32843013].

Composés actifs

Bioactive compounds include polyphenols such as catechin, epigallocatechin, and epicatechin [PMID:41895927]. Fruit peels contain eleagnine, myricetin rhamnoside, quercetin, linoleic acid, and oleic acid [PMID:32375072]. Essential oils from leaves and fruits contain various volatile compounds [PMID:34221505], and seed oil contains triglycerides, carbonyl, alkane, and alkene compounds [PMID:31058182].

Mécanisme d'action

The herb demonstrates antioxidant and anti-inflammatory effects by suppressing pro-inflammatory cytokines and NF-κB activation [PMID:32375072, PMID:34225016, PMID:42036000]. It may enhance the expression of Nrf2 [PMID:42036000, PMID:34900818] and inhibit α-glucosidase and α-amylase activities [PMID:33270256, PMID:32843013]. In muscle tissue, it promotes glucose uptake and elevates levels of glutathione, superoxide dismutase, and catalase [PMID:33270256].

Preuves cliniques

Preuve DType 2 Diabetes/Hyperglycemia

Fruit ethanol extract ameliorated hyperglycemia and elevated blood pressure in streptozotocin-induced diabetic rats via modulation of oxidative stress, NF-κB, and PPAR-γ [PMID:34225016]. Fruit pulp powder influenced Nrf2, SOD, CAT, and GST expressions in diabetic rats [PMID:34900818].

Preuve DCognitive Impairment

A fruit-supplemented diet enhanced cognitive functions and attenuated lipopolysaccharide-induced memory impairment and oxidative stress in mice [PMID:38624427]. Fruit extract showed neuroprotective effects against stress and LPS-induced behavioral impairments in mice [PMID:35867181].

Preuve DHypertension and Reproductive Function

Diet supplemented with fruit pulp improved sperm parameters, reproductive hormones, and antioxidant markers in hypertensive male rats [PMID:34591290].

Preuve DMalaria

Seed and pulp extracts demonstrated both suppressive and curative antimalarial properties in Albino mice inoculated with Plasmodium berghei [PMID:29269970].

Preuve DInflammation and Pain

Fruit peel extract significantly reduced abdominal writhing and paw edema in rodent models by inhibiting pro-inflammatory cytokines and COX-2 [PMID:32375072]. Seed oil demonstrated anti-inflammatory effects in carrageenan-induced acute inflammation and CFA-induced arthritis [PMID:42036000].

Sécurité et effets indésirables

The oral acute toxic dose of the pulp extract was found to be beyond 5000 mg/kg [PMID:29269970]. Peel ethanol extract (CAPEE) showed no sign of toxicity in mice at a dose of 2,000 mg/kg [PMID:30975003].

Grossesse et allaitement

Traditional consumption of the fruit pulp by pregnant women in south eastern Nigeria may serve as an intermittent preventive therapy against malaria infection [PMID:29269970].

Synthèse des preuves

The current evidence is based entirely on in vitro studies and animal models (rodents), representing a low overall strength of clinical evidence (Level D). No human clinical trials were provided.
