The Science Behind Yurika! & Why It Works

Medicinal Ingredients and Clinical Trials 

Yurika! - the certified botanical solution for menstrual cramps.

Note - menstrual cramps, period pain and primary dysmenorrhea are used interchangeably.

Yurika! Medicinal Ingredients
Yurika! is a unique compound of two therapeutic botanicals:

  1. Bitter Fennel Mill (Seed)
    - anti-spasmodic, analgesic, anti-inflammatory

  2. Ginger Rhizome
    - analgesic, anti-inflammatory, antiemetic, bio-enhancer

This post presents evidence that both bitter fennel seed and ginger rhizome have proven to relieve menstrual cramps. ⁣

In combination however, their synergism has greatly amplified the medicinal value.⁣

This is why women taking Yurika! regularly experience the complete prevention or elimination of period pain.

      DOI: 10.1111/pme.12853

      Objective: There has been no attempt to date to synthesize the available evidence for the efficacy of ginger for treating primary dysmenorrhea. This systematic review evaluates the current evidence for the effectiveness of ginger for treating primary dysmenorrhea.

      Method: Literature searches were conducted using 12 electronic databases including: PubMed, EMBASE, Cochrane Library, Korean databases, Chinese medical databases, and Indian scientific database

      Results: Initial searches yielded 29 articles. Of these original results, seven met specific selection criteria

      Conclusion: Collectively these RCTs [Registered Clinical Trials] provide suggestive evidence for the effectiveness of ginger powder during the first 3–4 days of menstrual cycle for primary dysmenorrhea.

      Purpose: The aim of the study was to compare the effect of mefenamic acid and ginger on pain management in primary dysmenorrhea.

      Methods: One hundred and twenty-two female students with moderate to severe primary dysmenorrhea were randomly allocated to the ginger and mefenamic groups in a randomized clinical trial.

      Conclusion: Ginger is as effective as mefenamic acid on pain relief in primary dysmenorrhea. Ginger does not have adverse effects and is an alternative treatment for primary dysmenorrhea.

      3. Ginger Reduces Menstrual Blood Loss Related to Iron Deficiency Anemia

      Ginger appears to be a highly effective treatment for the reduction of menstrual blood loss. This is important since up to 18 million young women in the United States experience iron deficiency anemia due to heavy menstrual bleeding.

      4. Ginger is a Bio-enhancer

      Bio-enhancers are chemical entities which promote and augment the bioavailability of the drugs which are mixed with them. In this case, ginger enhances the therapeutic value of bitter fennel.
