What are the morphological characteristics of this plant?

Prunus armeniaca has woody, deciduous branches characterized by long, lanceolate to ovate leaves with serrated margins and a distinctively pointed tip. The leaf surfaces are typically smooth and can vary from a bright green to a darker shade depending on the season. Small, white or pale pink flowers emerge from the woody stems in early spring, often appearing before the foliage fully develops. These blossoms are clustered in groups and feature five delicate petals surrounding a central cluster of stamens. The plant eventually produces oval, fleshy drupes that transition from green to a vibrant yellow or orange hue when ripe.

The Xiaoxuming decoction serves as another significant medicinal application involving this species. Additionally, researchers utilize 50% ethanolic extracts to isolate bioactive compounds for clinical study.

According to a study published by "Phytochemical analysis : PCA", Prunus armeniacica pomace is rich in polyphenolics including trans-lutein (14.1%), trans-zeaxanthin (10.5%), trans-ß-cryptoxanthin (11.6%), 13, cis-ß-carotene (6.5%), trans 9, cis-ß-carotene (18.4%), and ß-carotene (21.5%). The Prunus armeniacica kernel extract before detoxification contains 16.1% amygdaline and caused a 50.1% mortality rate, whereas the detoxified kernel with 1.4% amygdaline resulted in a 9.1% mortality rate. Prunus armeniacica pomace showed significant antidiaabetic-activity (p ≤ 0.05, n = 7/group) during acute (6 h), subchronic (8 days), and long-term (8 weeks) assessments. This pomace showed a more significant and dose-dependent increase in serum-insulin, CAT-levels, and body-weights compared to the detoxified kernel extract. The antidiaabetic-potentials of the pomace and detoxified-kernels are likely mediated via alpha-glucosidase inhibition and insulin-secretagogue effects.

What side effects this plant can have?

This plant can cause severe physiological harm including acid reflux symptoms, gastrointestinal dysmotility, and a high mortality rate due to cyanide poisoning. Ingesting the seeds can lead to significant digestive disruptions such as stomach pain and irregular bowel movements. The chemical compounds within the plant interfere with cellular respiration, which often results in rapid organ failure. If the toxic dose is large enough, the resulting systemic toxicity leads to a high mortality rate. These dangerous side effects make the consumption of its seeds extremely hazardous to human health.

According to a study published by "World journal of gastroenterology", the consumption of Prunus armeniacica was studied in 1303 Japanese individuals to examine its effects on GERD-related symptoms. Among these subjects, 392 individuals had a daily intake of ≥ 1 JA daily, while 911 subjects had none or occasional intake of < 1 JA daily. Those with daily JA intake had significantly lower total FSGS scores of 2.13 ± 3.14 compared to 2.70 ± 3.82 in the other group. Specifically, daily JA intake improved FSGS dysmotility scores from 1.46 ± 2.11 down to 1.05 ± 1.58, though the reflux score of 1.08 ± 1.90 did not differ significantly from 1.24 ± 2.11. Furthermore, GERD patients with a total FSGS score ≥ 8 were less frequent in the daily intake group at 6.1% versus 9.7% in those without daily intake. The improvement in dysmotility was specifically observed in non-elderly subjects with scores of 1.24 ± 1.68 versus 1.62 ± 2.22 and in H. pylori-negative subjects with scores of 0.99 ± 1.58 versus 1.57 ± 2.06.
