Ashwagandha
(Withania somnifera )
All five studies concluded that WS intervention resulted in greater score improvements (significantly in most cases) than placebo in outcomes on anxiety or stress scales.
Our results provide evidence indicating that key constituents in WS may have an important role in the development of pharmacological treatments for neurological disorders associated with GABAergic signaling dysfunction such as general anxiety disorders, sleep disturbances, muscle spasms, and seizures.
300 mg twice a day.
Final BAI scores (anxiety test) decreased by 56.5% in the Ashwagandha group. Significant differences between groups were also observed in mental health, concentration, fatigue, social functioning, vitality, and overall quality of life with the Ashwagandha group exhibiting greater clinical benefit. No serious adverse reactions were observed in either group.
250 mg 2x/day
500 mg/day for bipolar, effective.
Each capsule contained 300 mg of high-concentration full-spectrum extract from the root of the Ashwagandha plant. Each person took 2 capsules a day. The treatment group that was given the high-concentration full-spectrum Ashwagandha root extract exhibited a significant reduction in scores on all the stress-assessment scales on Day 60, relative to the placebo group. The serum cortisol levels were substantially reduced in the Ashwagandha group, relative to the placebo group. No serious adverse events were reported.
W. somnifera extract is effective in treating obsessive compulsive disorder
The results suggest the protective effect of WS in the management of ethanol (alcohol)withdrawal reactions.
Preliminary results suggest that Withania root extract can be used in the management sleep loss and associated oxidative stress.
Effective for anxiety
WSG also exhibited an antidepressant effect, comparable with that induced by imipramine in the 'behavioural despair' and 'learned helplessness' tests. The investigations support the use of WS as a mood stabilizer in clinical conditions of anxiety and depression
It has a Cognition Promoting Effect and was useful in children with memory deficit and in old age people loss of memory. It was also found useful in neurodegenerative diseases such as Parkinson's, Huntington's and Alzeimer's diseases. It has GABA mimetic effect and was shown to promote formation of dendrites. It has anxiolytic effect and improves energy levels and mitochondrial health. It is an anti-inflammatory and anti-arthritic agent and was found useful in clinical cases of Rheumatoid and Osteoarthritis.
1,250 mg/day × 10 days
All volunteers tolerated WS without any adverse event.
Safety and side effects
250 mg twice a day.
At 6 weeks, significantly more patients met a priori response criteria in the drug group (88.2%) as compared with the placebo group (50%). The drug was well-tolerated and did not occasion more adverse effects than did placebo. It is concluded that this ethanolic extract of Withania somnifera has useful anxiolytic potential and merits further investigation. This product is comparative to lorazepam in its ability to control anxiety.
This study provides scientific validation to the anxiolytic, anti-inflammatory and anti-apoptotic properties of ASH-WEX, which may serve as an effective dietary supplement for management of SD induced stress and associated functional impairments.
Conclusion Ashwagandha root extract is a natural compound with sleep-inducing potential, well tolerated and improves sleep quality and sleep onset latency in patients with insomnia at a dose of 300 mg extract twice daily. It could be of potential use to improve sleep parameters in patients with insomnia and anxiety, but need further large-scale studies.
An investigation into the stress-relieving and pharmacological actions of an ashwagandha (Withania somnifera) extract
A randomized, double-blind, placebo-controlled study
Abstract
Background:
Ashwagandha (Withania somnifera (L.) Dunal) is a herb traditionally used to reduce stress and enhance wellbeing. The aim of this study was to investigate its anxiolytic effects on adults with self-reported high stress and to examine potential mechanisms associated with its therapeutic effects.
Methods:
In this 60-day, randomized, double-blind, placebo-controlled study the stress-relieving and pharmacological activity of an ashwagandha extract was investigated in stressed, healthy adults. Sixty adults were randomly allocated to take either a placebo or 240 mg of a standardized ashwagandha extract (Shoden) once daily. Outcomes were measured using the Hamilton Anxiety Rating Scale (HAM-A), Depression, Anxiety, and Stress Scale -21 (DASS-21), and hormonal changes in cortisol, dehydroepiandrosterone-sulphate (DHEA-S), and testosterone.
Results:
All participants completed the trial with no adverse events reported. In comparison with the placebo, ashwagandha supplementation was associated with a statistically significant reduction in the HAM-A (P = .040) and a near-significant reduction in the DASS-21 (P = .096). Ashwagandha intake was also associated with greater reductions in morning cortisol (P < .001), and DHEA-S (P = .004) compared with the placebo. Testosterone levels increased in males (P = .038) but not females (P = .989) over time, although this change was not statistically significant compared with the placebo (P = .158).
Conclusions:
These findings suggest that ashwagandha's stress-relieving effects may occur via its moderating effect on the hypothalamus-pituitary-adrenal axis. However, further investigation utilizing larger sample sizes, diverse clinical and cultural populations, and varying treatment dosages are needed to substantiate these findings.

Brz - ashwagandha update:
had to stop - bummer.
definitely allergic. just like sk8ermama. i couldn't figure out why my allergies hadn't gone away even after the pollen count dropped way down. stopped the ashwagandha and my congestion and headaches subsided. not to mention i had a very tight chest feeling. very uncomfortable. my side effects are not uncommon from what i've learned. i may try again way down the road but now that i'm battling reflux, i don't want to complicate things. i've heard rhodiola is a similar adaptogen, but don't want to introduce anything new into my system right now.
Polly - The Ashwaganda and Suntheanine is making me feel spaced out but calm - which isn't a bad thing!
FH - I noticed that this product has a warning about using it if you have a thyroid condition. It turns out that Ashwag… raises thyroid hormones t3 and t4 BUT the black pepper extract lowers t3 and t4. Due to the instability in the effect of these components there is a thyroid warning. As I an a recovering subclinical hypothyroid patient I will stay away from this supplement. I also found that the piperine (black pepper extract) allows the extra absorbtion of medication in the digestive tract and although extensive research has not been conducted there is a number of medications that it has already been demonstrated to significantly elevate during use. I certainly do not want to start jacking around with my medication absorbtion. For right now the Ashwag… is out.
brokedowninohi - "The physical symptoms of anxiety were running rampant this morning and I decided to try ashgawandha. Made a trip to my "local" corporate grocery and picked up some "organic non-GMO" non-certified ashgawandha in 500 mg tablets, advertised as being 10% withanolides. It does not have any black pepper content so I supplemented some out of curiosity.
I swear that single tablet did more in a couple hours for relieving my physical anxiety than 5k run..."
"As for the ash, I've taken 1000 mg for the past two nights and slept like a baby. I haven't woken that refreshed or free of muscular tension in a while."
Lowered TSH, and rasied t3 and t4 (Thyroid enzymes)
administered daily for 20 days by gastric intubation increased serum 3,3',5-triiodothyronine (T3) and tetraiodothyronine (T4) concentrations

Ashwagandha-induced liver injury: A case series from Iceland and the US Drug-Induced Liver Injury Network.
In all but one case, normal function was resumed and rhodiola was a possible factor in one case. The final case left unreported - so not quite as bad as it all seems.
Efficacy and Safety of Ashwagandha (Withania somnifera) Root Extract in Insomnia and Anxiety: A Double-blind, Randomized, Placebo-controlled Study.
Abstract
Introduction Insomnia is a prevalent sleep disorder that can profoundly impact a person's physical health and mental wellbeing. Most of the currently available drugs for insomnia exert adverse effects. Hence, alternative herbal therapies could be effective in treating insomnia. Ashwagandha, a proven "Rasayana" from ancient Ayurveda is having the required potential to treat insomnia. Objective To determine the efficacy and safety of Ashwagandha root extract in patients with insomnia and anxiety. Methods This was a randomized, double-blind, placebo-controlled study conducted at Prakruti Hospital, Kalwa, Maharashtra, India. A total of 60 patients were randomly divided into two groups: test (n = 40) and placebo (n = 20) in a randomization ratio of 2:1. Test product was a capsule containing highest concentration full-spectrum Ashwagandha root extract 300 mg, and the placebo was an identical capsule containing starch. Both treatments were given twice daily with milk or water for 10 weeks. Sleep actigraphy (Respironics Philips) was used for assessment of sleep onset latency (SOL), total sleep time (TST), sleep efficiency (SE) and wake after sleep onset (WASO). Other assessments were total time in bed (sleep log), mental alertness on rising, sleep quality, Pittsburgh Sleep Quality Index (PSQI), and Hamilton Anxiety Rating Scale (HAM-A) scales. Results Two patients, one from each group, did not complete study and the per-protocol dataset (n = 58) included 29 and 19 patients from test and placebo, respectively. The baseline parameters were similar in the two groups at baseline. The sleep onset latency was improved in both test and placebo at five and 10 weeks. However, the SOL was significantly shorter (p, 0.019) after 10 weeks with test [29.00 (7.14)] compared to placebo [33.94 (7.65)]. Also, significant improvement in SE scores was observed with Ashwagandha which was 75.63 (2.70) for test at the baseline and increased to 83.48 (2.83) after 10 weeks, whereas for placebo the SE scores changed from 75.14 (3.73) at baseline to 79.68 (3.59) after 10 weeks. Similarly, significant improvement in sleep quality was observed with test compared to placebo (p, 0.002). Significant improvement was observed in all other sleep parameters, i.e., SOL, SE, PSQI and anxiety (HAM-A scores) with Ashwagandha root extract treatment for 10 weeks. Conclusion Ashwagandha root extract is a natural compound with sleep-inducing potential, well tolerated and improves sleep quality and sleep onset latency in patients with insomnia at a dose of 300 mg extract twice daily. It could be of potential use to improve sleep parameters in patients with insomnia and anxiety, but need further large-scale studies.
Note - These results may be statistically significant but I am not impressed. The improvement on sleep averages around 5% more than placebo and this is in healthy individuals not someone going through withdrawal. Also, like many have noted on this site, the effects tend to wear off after a few weeks.
