Alternanthera sp.

Recommended Posts

Hi all, I would like to know more on the alternanthera purple knight . I am curious because last year my dog was getting ready to go into labour with her puppy's and she was pacing the garden, looking a bit beside herself when she started eating the small white flowers off this plant. I was instantly concerned and stopped her from consuming more than the two she had already eaten. I thought it best at the time to know what she had eaten, so I tried some. I put a flower in my mouth and chewed it a little, spitting out the hard pulp and juice and only swallowing a residual amount. I felt high and buzzy with a terrible prickly feeling in my mouth and throat, this lasted for hours. My dog survived and had a trouble free birth, I survived and want to know more :wink:. It is also commonly known as joyweed, wonder why?

Anybody else had experiences with this sp. of alternanthera?

What does "high and buzzy" mean?

I have no idea about the effects you report but if you know how to reproduce this plant I'd be interested in growing it :) -ef

Little does she know, her entire litter will grow up being morbid joyweed addicts who are unable to integrate into society.

I knew someone who knew someone that smoked shard while pregnant and their kid was born with all of it's guts on the outside of it's body.

Lol, I visited woodwoman a place on the weekend and helped identify this as alternanthera. I was wondering if it could be alternanthia lehmannii - some websites list this as an aya additive but people seem unsure which part of the plant to use. The leaves darken on sunlight which would mean a color match. There is also mention of an unknown alternanthera plant (I think it said from Warwick, qld) which contains some goodies but cannot find that website now to refer back...

I've looked into this plant before, but no dried herb is available commercially. Was the buzz pleasurable, and what would you compare it to? Plain anxiolytics rarely make me feel high, maybe relaxed and drowsy. I'd like to hear more on your evaluation of it's effects.

Here are the abstracts I came across awhile back:

Anxiolytic and anticonvulsant activity of methanol extract of leaves of Alternanthera brasiliana (L.) Kuntze (Amaranthaceae) in laboratory animals.
Abstract

Anxiety related disorders are the most common mental illnesses and major cause of disability in man. Anxiolytic activity of methanol extract of leaves of A. brasiliana (L.) Kuntze (MEAB) was evaluated using hole board (HB), open field (OF), elevated plus maze (EPM) and light/dark exploration test (LDE) in mice. Its locomotor activity was studied using actophotometer and anticonvulsant effect was studied using maximal electroshock-induced seizures and pentylenetetrazole-induced seizures in mice. Single oral administration of MEAB at different doses (100, 300 and 600 mg/kg, ip) significantly increased the number and duration of head poking in the HB test; rearing, assisted rearing and number of square traveled in the OF test; entries and time spent in open arm in the EPM test; time spent in lighted box, and numbers of crossings and transfer latency time in the LDE test. There was significant reduction in the time spent in close arm in the EPM test and time spent in dark box in LDE test. In the actophotometer, the activity count was reduced in MEAB and diazepam treated group than control group. All the three doses of the extract significantly reduced the duration of seizures induced by pentylenetetrazole (chemoshock convulsion). However, the extract did not show any appreciable effect in electroshock convulsion model. The results of the present study suggest promising anxiolytic and anticonvulsant activity of MEAB which might be accredited to different phytoconstituents like alkaloids, steroids and triterpenes present in the methanol extract of A. brasiliana .

Evaluation of the pharmacological activity of the Alternanthera brasiliana aqueous extract.
Abstract
CONTEXT:

Alternanthera brasiliana (L.) Kuntze (Amarantaceae) is widely used in Brazilian traditional medicine as an analgesic, anti-inflammatory and antibacterial.

OBJECTIVE:

To investigate the potential anti-inflammatory, analgesic, anxiolytic, and locomotor effect of the infusions in preclinical models.

MATERIALS AND METHODS:

Anti-inflammatory activity was evaluated by a carrageenan-induced pleurisy test in Wistar rats (200 and 400 mg/kg, n = 6-7). Analgesic activity was evaluated by the number of abdominal contractions induced by 0.6% acetic acid administered to Swiss mice (25, 50, 100, 200, and 400 mg/kg, n = 10). Effects on the central nervous system (CNS) were evaluated in Wistar rats (100, 200, and 400 mg/kg, n = 10) using open field and plus maze models.

RESULTS AND DISCUSSION:

Possible anti-inflammatory activity was indicated by the significant reduction of 19.8% for 200 mg/kg (p < 0.05) and 23.9% for 400 mg/kg (p < 0.05) of polymorphonuclear cells in pleural exudate. Analgesic activity was suggested by the significant reduction (p < 0.01) of number of abdominal contractions for all doses under study. No anxiolytic effect was noted, but there was an increase in the number of rearings in the group of rats treated with 100 mg/kg dose (p < 0.05).

CONCLUSIONS:

Our findings suggest that the aqueous extract of the leaves of A. brasiliana has a potential pharmacological effect on inflammation and pain.
