Prunus Persica Herb (Prunus persica): Benefits, Dosage, Safety & Evidence

Questions fréquentes

What are the medicinal uses of Prunus persica leaves?

In traditional folk medicine, Prunus persica leaves and bark are primarily used as a digestive sedative to soothe stomach upset and as an antitussive for respiratory conditions like whooping cough. It is also utilized as a remedy for kidney and bladder irritation. These uses are supported by traditional evidence rather than rigorous clinical trials (Evidence Level: C).

How does Prunus persica work as a medicinal herb?

Prunus persica contains cyanogenic glycosides, specifically prunasin and amygdalin. Upon metabolism, these compounds hydrolyze to release small amounts of hydrocyanic acid. This action is believed to suppress the cough reflex (antitussive) and relax smooth muscle in the digestive tract, providing a sedative effect. Evidence Level: C.

What is the recommended dosage for Prunus persica leaf tea?

The standard adult dosage for Prunus persica leaf tea is 2 to 4 grams of dried leaf steeped in hot water, typically taken up to three times daily. The fruit is considered safe for consumption as food. Because the leaves contain cyanogenic glycosides, users should strictly adhere to recommended dosages to avoid potential toxicity. Evidence Level: Traditional.

Is Prunus persica safe to use during pregnancy?

Prunus persica leaf and bark extracts are considered unsafe during pregnancy. The plant contains prunasin and amygdalin, which are cyanogenic glycosides that can metabolize into cyanide. This poses a risk of fetal toxicity. While the fruit is safe as food, pregnant women should avoid medicinal preparations of the leaves, bark, or seeds. Evidence Level: C.

Does Prunus persica interact with any medications?

Due to the presence of cyanogenic glycosides, Prunus persica may theoretically interact with drugs metabolized by the liver or medications that affect respiratory function. High doses could potentiate the effects of CNS depressants. However, specific clinical drug interaction studies are lacking (Evidence Level: C). Patients should avoid combining it with other herbs containing cyanogenic compounds.

Are Prunus persica seeds safe to consume?

No, the seeds (kernels) of Prunus persica are potentially toxic. They contain high concentrations of amygdalin, a cyanogenic glycoside. When metabolized, this compound releases cyanide, which can cause acute toxicity. While the leaves are used in controlled doses, seed extracts should be strictly avoided due to the risk of cyanide poisoning. Evidence Level: C.

Résumé

Prunus persica (peach) is a globally cultivated stone fruit of the Rosaceae family containing various nutritive and bioactive substances [PMID:31860205, PMID:36465719].

Contexte

Prunus persica is a major agricultural stone fruit crop from the Rosaceae family that has been cultivated for over 7,500 years, with archaeological evidence of domestication in China dating back approximately 8,000 BP [PMID:40567591, PMID:25192436, PMID:39048957].

Composés actifs

Peach fruits contain a complex of nutritive and biologically active substances [PMID:31860205]. Bioactive components found in peach by-products (peel, stone, and pomace) include lipids, proteins, phenolics, and fiber [PMID:36465719]. Specific metabolites identified in honey peach include quercitrin, plantagoside, 3-p-coumaroylquinic acid, procyanidin, and quinic acid [PMID:35761534]. The monoterpene linalool is a major contributor to aroma and flavor [PMID:30481327].

Preuves cliniques

Preuve DAllergy/Sensitization

Sensitization to peach tree pollen (PTP) and Prunus persica 9 (Pru p 9) occurred in 20% of children and adolescents studied, with most cases presenting as rhinitis or rhinoconjunctivitis [PMID:31533105].

Sécurité et effets indésirables

Peach tree pollen (PTP) and the allergen Prunus persica 9 (Pru p 9) can induce sensitization and clinical symptoms such as rhinitis and rhinoconjunctivitis in children and adolescents [PMID:31533105].

Synthèse des preuves

The available evidence is primarily focused on botanical genetics, agricultural pathology, and food science, with limited clinical data restricted to allergen sensitization studies.
