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. Amazing

      I'm guessing my first review didn't make it because of the dose I listed taking. The 300mg/day dose cited in the NIH study was for memory enhancement in normal healthy adults. I use this for the mood effects, and am not a normal nor a healthy adult. It takes me 3,000 mg per day to get a functional response. The 300mg/day dose has nothing to do with the mood effects, and if that dose works for you, great. Many others report that effect too. My side effects are slight dizziness and slight disassociation. I worked up to that dose from the 100mg 3x/day, starting higher could possibly be dangerous. If this review presents more risk than help, or conflicts with some policy, I'm fine with it not being posted. I'm just happy to have a product that works. on 2nd Feb 2019

    2. Nothing wrong with it

      Stronger NMDA antagonism than I expected, not subtle at all. NMDA antagonism gets stronger when combined with the NMDA antagonist Huperzine A, and even stronger when combined with tianeptine as well.

      May not be extremely suitable for racetam combinations because of NMDA antagonism.

    3. Amazing

      I haven't had the opportunity to try this herb from any other vendor and I don't have a reason to! I use this to help alleviate low mood and the effect is subtle but noticeable. Taste is phenomenal (great surprise). Shipping is quick even to canada; i received my package within 9-10 days.
      Thank you so much ND and I look forward to doing more business with you.

    4. Great product.

      I really like Polygala for occasional use. It seems to work really well on days when I have had a poor nights sleep, it makes me feel more awake/alert with improved cognitive ability which is usually EXTREMELY lacking for me when I don't sleep well, it also helps with irritability which I really struggle with when I haven't slept well. on 15th Mar 2018

    5. Does help

      especially when combined with agmatine sulfate. It's not a profound effect but noticeable on 10th Dec 2017

    6. When I feel weird

      I use this when my mind isn't my bitch. works good ! on 9th Dec 2017

    7. very suprising

      helping my mood. I am really glad i gave this a try. on 24th Sep 2017

    8. Adoro isso!

      Chegou muito rápido! O NP estão de parabéns pelo seu atendimento também. Levo 2 ou 3 vezes por dia. No quarto dia que experimentei, realmente sentir como um baita de um antidepressivo. Você não senti mais anedonia, raiva...Tomando isso, consegui me livrar de uma medicação antidepressiva. Melhorou meu sono também. Minha mãe também está tomando e vendo ótimos resultados! on 20th Sep 2017

    9. Impressive !

      This is a very impressive herbal product. Very smooth lifting of mood. Increased feelings of comfort, enjoyment, playfulness. No discernible negative side-effects. It is gentle and effective, but I would not recommend exceeding recommended dose, or using too frequently. I choose to use it only 2 or 3 times a week. Under better life circumstances, or if absolute clarity were the goal, I would keep it on the shelf until it's needed. Fantastic product, thank you ND. on 4th May 2017

    10. It certainly works.

      This has literally been the only thing that has ever helped. I take this daily with a fairly large dose of omega 3 EPA/DHA. I have definitely noticed a difference and it absolutely is a positive one. I give it 4 stars instead of 5 only because it's not a miracle in powder form, it's not like all of my problems with my brain function just disappeared, but I will say that if you try this you do need to give it time. I've been taking it for a few weeks now and I am just starting to get the full effects. I recommend waiting at least a month before making any judgment. Either way, I am glad I tried this, it really is helping me navigate my mind and life. on 26th Apr 2017
