How does Aerva lanata work for kidney stones?

Aerva lanata contains active compounds including flavonoids, saponins, and alkaloids that contribute to its anti-urolithiatic properties. The herb is believed to inhibit calcium oxalate crystal formation and promote the dissolution of existing stones. Its diuretic action increases urine output, which helps flush the urinary tract. Additionally, the plant exhibits anti-inflammatory and antimicrobial properties that may support overall urinary tract health. Evidence Level: C (preclinical and traditional use data).

Does Aerva lanata interact with any medications?

There is limited clinical research on Aerva lanata drug interactions. Due to its diuretic properties, it may potentially enhance the effects of diuretic medications, leading to increased fluid loss and electrolyte imbalances. Patients taking lithium or medications affected by urinary pH changes should exercise caution. Always consult a healthcare provider before combining Aerva lanata with prescription medications. Evidence Level: C (theoretical based on mechanism).

What is the recommended dosage of Aerva lanata?

Traditional Ayurvedic practice recommends 5-10 grams of dried Aerva lanata herb prepared as a decoction, taken once or twice daily. Standardized extracts are typically dosed at 500mg twice daily. The herb is commonly prepared as a tea or taken in capsule form. Dosage should be adjusted based on individual tolerance and the specific condition being treated. Consult a qualified practitioner for personalized dosing. Evidence Level: Traditional.

Is Aerva lanata safe during pregnancy?

Aerva lanata is considered unsafe during pregnancy and should be avoided. The herb's strong diuretic properties and potential effects on smooth muscle may pose risks to fetal development and pregnancy maintenance. There is insufficient safety data for breastfeeding women, so avoidance is also recommended during lactation. Women who are pregnant or planning pregnancy should consult their healthcare provider before using any herbal supplements. Evidence Level: C.

What are the side effects of Aerva lanata?

Aerva lanata is generally well-tolerated when used at recommended doses. Reported side effects are mild and include increased urination due to its diuretic action and occasional nausea. Some individuals may experience gastrointestinal discomfort. The herb should be avoided in cases of severe kidney disease without medical supervision, as its effects on kidney function require monitoring. Discontinue use if adverse reactions occur. Evidence Level: C (traditional use and limited clinical data).

Résumé

Aerva lanata is a medicinal plant used in traditional systems like Ayurveda and Siddha for various therapeutic purposes, including the treatment of urolithiasis and respiratory issues [PMID:22279378, PMID:20979430].

Contexte

Aerva lanata (L.) Juss. ex Schult (family Amaranthaceae), locally known as 'bui', is an erect or prostrate undershrub with a long tap-root, found throughout India [PMID:22279378].

Usages traditionnels

Traditionally used for cough, sore throat, asthma [PMID:35143934], strangury, headache, and urolithiasis [PMID:22279378]. In Nigeria, it is used for lithiasis, renal disorder, haematemesis, bronchitis, nasal bleeding, scorpion stings, fractures, and spermatorrhoea [PMID:28668647]. It is also consumed as a tonic by pregnant women to relieve stomach pains and prevent miscarriage [PMID:37122890].

Composés actifs

Phytochemical constituents include alkaloids (ervine, methylervine, ervoside, aervine, methylaervine, aervoside, ervolanine, and aervolanine), flavonoids (kaempferol, quercetin, isorhamnetin, persinol, persinosides A and B), methyl grevillate, lupeol, lupeol acetate, benzoic acid, β-sitosteryl acetate, and tannic acid [PMID:22279378]. Other identified components include ferulic acid and β-carboline [PMID:24681590], as well as various steroids [PMID:23569807] and phenolic acids [PMID:34201147].

Mécanisme d'action

In allergic asthmatic mice, the ethyl acetate extract lowered levels of inflammatory modulator TNF-α and IgE antibodies, and reduced interleukin 4, 5, and 13 [PMID:35143934]. In osteosarcoma cell lines (Saos2), it exerts an oncolytic effect via the apoptotic signaling pathway [PMID:38738026]. It also demonstrates the ability to inhibit diabetes-related enzymes α-amylase and α-glucosidase [PMID:30356437].

Preuves cliniques

Preuve DUrolithiasis

Isolated compounds quercetin and betulin significantly increased urine volume in ethylene glycol-induced urolithiasis rat models [PMID:29169771].

Preuve DAllergic Asthma

Ethyl acetate extract ameliorated the count of inflammatory cells in blood and broncho-alveolar lavage fluid (BALF) in mice [PMID:35143934].

Preuve DType-II Diabetes

A partially purified alkaloid fraction from roots caused a significant reduction in serum glucose levels in rats [PMID:23527955].

Preuve DHepatotoxicity

Petroleum ether extractable fraction reversed histopathological changes and restored liver marker enzymes in CCl4-induced rat models [PMID:21783628].

Preuve DOsteosarcoma

Extract demonstrated a dose-dependent decrease in Saos2 cell proliferation [PMID:38738026].

Sécurité et effets indésirables

In Ayurveda, Aerva lanata is not prescribed for long-term use due to beliefs that it may produce structural changes in the urinary tract leading to renal failure [PMID:23225960]. Sub-chronic toxicity tests in rats (40-1000mg/kg for 90 days) were conducted to evaluate its safety profile [PMID:28668647].

Grossesse et allaitement

Consumed as a tonic by pregnant women to relieve stomach pains and prevent miscarriage [PMID:37122890]; however, an experimental study in pregnant rats showed that high doses (1000 mg/kg) significantly reduced the number of pups per litter and indicated anti-fertility and anti-implantation activities [PMID:37122890].

Synthèse des preuves

The current evidence is primarily based on in vitro studies and animal models (Level D), demonstrating significant pharmacological potential in anti-inflammatory, anti-urolithiatic, and anti-diabetic activities, but lacks human clinical trial data.
