Wild Asparagus

Generic name: Asparagus Racemosus (Willd.)
Brand names: Abhiru, Satavari, Shatavari

Usage of Wild Asparagus

A. racemosus is often used in polyherbal formulations, making observed effects in studies difficult to attribute to a single product.

Cancer

Animal and in vitro data

In vitro studies in human cancer cell lines and experiments in rodents describe apoptotic and antioxidant activity of A. racemosus root extractBhUTAni 2010, Karuna 2017, Kongkaneramit 2011, Smita 2017, Verma 2014. Antioxidant activity was also considered to play a role in prevention of isoniazid-induced hepatotoxicity in an animal study.Palanisamy 2012 Furthermore, pretreatment of rats with an aqueous root extract of A. racemosus in one study prevented hepatocarcinogenesis,Agrawal 2008 while in another experiment, reductions were observed in viable tumor cell counts.Mitra 2012

CNS

Animal data

Studies in rodent models have been conducted to assess effects of A. racemosus on stress and learning and memory, primarily using the methanolic extract of A. racemosus root.Garabadu 2014, Ojha 2010, Singh 2009

Evaluation of levels of serotonin, norepinephrine, and other monoamines suggest a centrally acting mechanism,Garabadu 2014, Krishnamurthy 2013, Ojha 2010, Pahwa 2016, Singh 2009 possibly related to the saponin content of the extract.Meena 2011 In one animal experiment, flumazenil atTenuated the effect of A. racemosus extract.Garabadu 2014

Diabetes

Animal data

In a study in rats with induced type 2 diabetes, ethanol extracts of A. racemosus roots administered over 28 days decreased serum glucose and increased pancreatic insulin, plasma insulin, liver glycogen, and total oxidant status.Hannan 2012

Diuretic effects

Animal data

A diuretic effect, with increased excretion of potassium, phosphate, and chloride, was demonstrated in a study in rats.Kumar 2010

Endocrine (estrogen/prolactin) effects

Animal data

Studies in rodents suggest estrogenic effects of A. racemosus extracts on female mammary glands as well as genital organs in adult pregnant rats.Pandey 2018, Singh 2016 Increases in plasma prolactin and milk production have been demonstrated in a study in buffaloes, suggesting a galactopoietic role.Singh 2012

Clinical data

Limited clinical studies have been published in peer-reviewed literature. One study reported no effect on follicular growth, development, or ovulation with use of shatavari compared with clomiphene citrate.Pandey 2018

Another clinical study (N=60) evaluated A. racemosus as a galactogogue and reported increases in prolactin in addition to positive findings for secondary outcome measures (satisfaction of the mother regarding the state of lactation and infant well-being and happiness).Gupta 2011

Gastric emptying

Clinical data

An older, small clinical study (N=8) compared A. racemosus (2 g of powdered root) to metoclopramide (10 mg tablet) with respect to gastric emptying time, with no difference reported.Dalvi 1990

Hypercholesterolemia

Animal data

In hypercholesteremic rats fed powdered A. racemosus, lipid profiles were improved and increases in hepatic hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase activity and bile acid were observed.Visavadiya 2009

Immunomodulatory activity

Animal and in vitro data

In in vitro and animal studies, A. racemosus extracts have demonstrated effects on proinflammatory cytokines and other immune factors (eg, interleukins, tumor necrosis factor [TNF], immunoglobulin G).Pise 2015, Sidiq 2011, Singh 2016, Thakur 2012, Tiwari 2017 Immune stimulation was demonstrated in a study of immunosuppressed animals,Sharma 2011 and proinflammatory cytokines were inhibited in mice with swimming-induced stress.Kanwar 2010 TNF-alpha was inhibited by a liposomal preparation of A. racemosus, with greater anti-inflammatory action at 0.1 mcg/mL than at higher concentrations.Plangsombat 2016

Infections

Animal and in vitro data

In vitro tests and screening studies suggest that A. racemosus possesses antifungal activity, including against Candida and Malassezia yeasts.Onlom 2014, Panghal 2011, Uma 2009 However, screening studies have produced equivocal results for antibacterial effects (possibly Dependent on the extraction method), with one study reporting A. racemosus HAD the least antimicrobial activity against human uropathogens,Narayanan 2011 and another study finding activity against all clinical isolates tested.Panghal 2011 In one screening study, activity in human CD4 T-cell lines infected with HIV was reported for saponins from A. racemosus.Sabde 2011

Toxicity of A. racemosus to mosquitoes (larvae and adults)Govindarajan 2014 and in leishmanial infections has been reported.Kaur 2014, Sachdeva 2017, Sachdeva 2014

Osteoclast inhibition

In vitro data

Limited inhibition of osteoclasts has been demonstrated in vitro.Di Pompo 2014

Wild Asparagus side effects

Clinical studies and case reports are lacking to provide information regarding adverse effects. The plant is considered safe by Ayurvedic practitioners.Singh 2016 In frogs, an alcoholic extract was reported to have positive ionotropic and chronotropic effects, with cardiac arrest occurring with high doses.Singh 2016

Before taking Wild Asparagus

Information is lacking. Shatavari is regarded as safe for use during pregnancy and lactation by Ayurvedic practitioners,Singh 2016 but the plant is not listed as having GRAS status by the FDA.Forinash 2012 In rats, teratogenic effects have been reported for the methanol extract.Singh 2016

Limited studies have been conducted evaluating the galactogogue effect of A. racemosus.Gupta 2011, Sharma 1996

How to use Wild Asparagus

There are no quality clinical trials to provide doSage recommendations.

In an older study, 2 g of powdered A. racemosus root was given to healthy volunteers to evaluate gastric emptying time.Dalvi 1990 In a small study evaluating effects on lactation, lactating mothers received 60 mg/kg/day of A. racemosus root powder orally for 30 days.Gupta 2011

Higher than product-specified doses should be avoided due to the potential for cardiac effects.Singh 2016

Warnings

Studies in rats suggest dosages of 3,200 mg/kg of aqueous extract of the roots is nonlethal. Subacute, long-term toxicity studies show no changes in physiological or biological measures in rats.Kumar 2010, Singh 2016 In rats, teratogenic effects have been reported for the methanol extract.Singh 2016

What other drugs will affect Wild Asparagus

Case reports of interactions are lacking. An in vitro experiment suggests the possibility of interactions with drugs dependent on CYP3A4 metabolic pathways.(Patil 2014)
