Polygala tenuifolia 20:1 Extract Powder (Yuan Zhi)

  • Product Description

    Polygala Tenuifolia Powder

    Polygala tenuifolia 20:1 Extract Benefits and Uses

    Sometimes referred to as Thinleaf Milkwort, Yuan Zhi, or Chinese Senega, Polygala tenuifolia is a root used in traditional Chinese medicine. Early animal research suggests that it may have mood boosting properties and promote brain health. Additional animal research has suggested that Polygala tenuifolia may also have adaptogen-like properties and therefore increases nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF). Additionally, it may improve spatial organization/recognition and increase cognitive ability.

    Polygala tenuifolia 20:1 Extract Dosage

    As a dietary supplement, take 100mg of Polygala tenuifolia Extract three times daily.

    Product contains one (1) 30g (300 servings) or 60g (600 servings) jar of Polygala tenuifolia 20:1 Extract Powder (Dual Water/Ethanol Extraction)

    1. Good Shipping Time

      Product arrived on time. The effects are good, but not mind blowing by any means. I imagine this herb works best if taken over a longer period of time. I would consider mixing this with a reishi extract to enhance the Shen effects. It's an ongoing experiment, I've sampled many different herbs to see if I notice a difference. Cinnamon, for example, can take up to a month to start working. Good for the hippocampus. on 2nd Feb 2017

    2. Great Polygala Extract!

      I immediately recognized the unique signature of Polygala root with 50 mg on the tongue
      (intense pungent and bitter aftertaste). I've used this great Chinese herb many times in decoction and tincture and I'm pleased with this highly concentrated extract.

      "The ancient name for this herb is the “Will Strengthener.” The herb is believed to have the ability to strengthen that part of the psyche which we call the “Will.” (Teaguarden 1996)

      Thanks for the fast shipping to Canada!

    4. Changed my life

      I was almost ready to see a dr and try anti-depressants but decided I'd check out some other options and found this stuff. I went from being moody, depressed, and generally anxious all the time to feeling totally normal. Life has been so much more manageable since I started taking this and I actually feel like I can cope for the first time in my life. This has seriously done wonders for me and I'd recommend it to anyone struggling to get through the day. on 6th Dec 2016

    5. Wow 2 minutes and it started working.

      Wow 2 minutes and it started working. Within 2 minutes it started working. I feel awesome. I just received it almost 25-30 days from USA to India. on 23rd Oct 2016

    6. Boosted mood and cognition

      To me this product made a big difference in my overall mood and made it easier to stay engaged in conversation while attending social events. The world seems more fluently navigation-able. on 22nd Oct 2016

    7. Wowzers!

      Good stuff. Combine 150 mg of this with L-taurine twice a day and watch your mood, focus, and cognitive function take off like Usain Bolt on amphetamine! on 21st Oct 2016

    8. Great product and value

      I'm very impressed with this substance so far (5 days in). It definitely manifests rapid anti-depressive effects in my experience. It also feels very clean and balanced and doesn't really have any side effects so far. The effects are also pretty acute, so I think it will be useful in specific situations as well as for those wishing to take it regularly. I've been sticking to the recommended dosage regime (100 3x) and I find it pairs pretty well with caffeine beverages for pick me up effects. on 3rd Oct 2016

    9. only on day 2, must say I'm impressed

      After previously trying Nyles7's extract, I've now pitched it (still had a good 40 grams left at least) and am using ND's instead. It's totally different (better) in terms of perceptible effects. It's like I imagine an ideal antidepressant to be. Sure to be a staple in many people's' nootropic regimen soon.

      HOWEVER on that note - I would steer clear of any monoaminergics used in tandem with this, to reduce propensity for psychosis (on dopaminergics), hypertension (noradrenergics), or hospitalizing (serotonergics) symptoms.

      Having said that, I'm looking forward to seeing other people's reports. Very confused as to why this wasn't in the nootropics scene until recently.

    10. Amazing! Wish I found this twenty years ago.

      Within a few days of using this product, anhedonia was the first neurological symptom to subside. Cognition is noticeably enhanced and brain fog is rapidly lifting. For the first time in years, learned helplessness is rapidly attenuating -- I feel like living life again after a difficult break-up of a year long relationship that occurred one month ago.

      It seems to be having a positive effect on sleep architecture as well (even had several lucid dream experiences the past few evenings). Slow wave sleep is noticeably enhanced as well -- I feel extremely refreshed in the morning as opposed to my usual grogginess and look forward to my day rather than dreading it.

      As opposed to pharmaceutical psychiatric drugs, this feels balanced and natural.
      SSRI's cause paresthesias, akathisia, and sexual anhedonia.
      Norepinephrine and/or dopamine reuptake inhibitors cause sympathomimetic side effects.
      Haven't noticed any nasty anticholinergic side effects either.

      Dopamine reuptake inhibitors have a "pushy" feel to them -- Polygala lacks the "edgy push" of typical dopaminergics and almost has an entactogenic/entheogenic feel to it.

      I'm extremely impressed with the quality of the product as well -- finely milled, excellent packaging, prompt customer service. Polygala will now become a permanent addition to my nootropic/psychiatric stack: I'm only a few days in and am looking forward to neurological benefits in the years to come. MANY THANKS Nootropics Depot for discovering, researching, and providing this quality "treasure" from China!
      I will be recommending this product to family, friends, and co-workers.
      Two question: Should I cycle, or can it be used on a daily basis?

      Thanks Again!!!
