Important safety information - please read before use

Buckwheat is a food, but it is also a recognized allergen - a few cautions matter.

  • Allergy: buckwheat can cause serious allergic reactions, including anaphylaxis, and the hull in particular - as dust from husks and buckwheat-hull pillows - is a known trigger for asthma and allergy - do NOT use it if you are allergic to buckwheat.
  • Sunlight sensitivity: buckwheat naturally contains a compound called fagopyrin (found mainly in the green parts and less in the hull) that can make the skin more sensitive to sunlight - be cautious with strong sun and stop if your skin reacts.
  • Blood thinners: buckwheat contains rutin, so talk to your practitioner if you take a blood thinner.
  • Pregnancy / nursing: ordinary food amounts are one thing, but for a concentrated extract consult a qualified healthcare practitioner first.
  • Contains alcohol. Do not give it to infants or young children. If you take any medication or have a medical condition, consult a qualified healthcare practitioner before use. Keep out of reach of children.

Frequently Asked Questions about Buckwheat Extract
What is Buckwheat (Fagopyrum esculentum) hull extract?
Buckwheat hull extract is a liquid extract of the dried hulls - the outer husk of the buckwheat seed - of Fagopyrum esculentum, common buckwheat, a pseudocereal of the Polygonaceae family. You may see it under an older botanical name, Polygonum fagopyrum, which is a synonym for the same plant. Despite the name, buckwheat is not a wheat or a grass. This tincture is extracted with organic alcohol. Two things are worth knowing: this is the buckwheat hull (Fagopyrum esculentum), a different part from our Buckwheat Seed (the same plant) and a different plant from Jin Qiao Mai (Fagopyrum dibotrys, golden buckwheat), which we sell separately; and buckwheat is a recognized allergen - the hull in particular is used to fill pillows, and buckwheat-hull dust is a known trigger for asthma and allergy - so please read the safety notes below.
What is the difference between the tincture and alcohol-free versions?
Both are liquid extracts of the same Fagopyrum esculentum hull; only the solvent differs. This tincture uses organic alcohol with vegetable glycerin and water, the classic conventional method that yields a super-concentrated extract with a long shelf life. The alcohol-free version is a glycerite made with vegetable glycerin and crystal clear water instead, for those who prefer to avoid alcohol. Choose the tincture for a traditional alcohol-extracted format; choose the glycerite if you prefer no alcohol. The botanical inside is identical. Please follow the safety notes for both.
Is the buckwheat hull the same as the buckwheat seed or Jin Qiao Mai?
No - a few buckwheat products are easy to mix up, so it helps to be clear. Buckwheat hulls and buckwheat seed come from the same plant, Fagopyrum esculentum (common buckwheat) - the hull is the outer husk and the seed is the grain (richer in rutin and, when sprouted, in fagopyrin) - we offer them separately. You may see the hull listed under the older name Polygonum fagopyrum, which is just a synonym for Fagopyrum esculentum. Jin Qiao Mai is a different species, Fagopyrum dibotrys (golden buckwheat), and Tartary buckwheat is Fagopyrum tataricum - different plants again. We label ours clearly as buckwheat hulls (Fagopyrum esculentum) so it is not confused with the seed or with the other buckwheats.
How do I use Buckwheat hull liquid extract?
Shake well first. Use the number of drops and the frequency shown on the label, in a little water, tea or juice, or as directed by your practitioner. Because this is an alcohol tincture, adding it to water softens the taste. Do not exceed the suggested serving. Because buckwheat is a recognized allergen, please read the safety information below before use. Store in a cool, dry place away from direct light.
Is Buckwheat hull right for everyone? Safety information.
Please read this carefully. Buckwheat is a food, but it is also a recognized allergen and a few cautions matter. Allergy: buckwheat can cause serious allergic reactions, including anaphylaxis, and the hull in particular - as dust from husks and buckwheat-hull pillows - is a known trigger for asthma and allergy, so do NOT use it if you are allergic to buckwheat. Sunlight sensitivity: buckwheat naturally contains a compound called fagopyrin (found mainly in the green parts and less in the hull) that can make the skin more sensitive to sunlight; be cautious with strong sun and stop if your skin reacts. Blood thinners: buckwheat contains rutin, so talk to your practitioner if you take a blood thinner. Pregnancy and nursing: ordinary food amounts are one thing, but for a concentrated extract consult a qualified healthcare practitioner first. Do not give it to infants or young children. If you take any medication or have a medical condition, consult a qualified healthcare practitioner before use. Keep out of reach of children.

Our Buckwheat (Polygonum Fagopyrum) Hulls is selected from regions with optimal growing conditions to support a high concentration of active constituents. We work only with trusted suppliers and focus on sourcing clean, well-preserved botanical material suitable for high-quality liquid extraction.

As a solvent, we use alcohol to preserve the integrity of the extract and support a clean extraction process.
To verify botanical identity and ensure consistency, all raw materials are tested in our laboratory using established analytical techniques. These include High-Performance Thin-Layer Chromatography (HPTLC) for plant authentication and fingerprinting, or Fourier-Transform Infrared Spectroscopy (FTIR) and other in-house methods. Our approach is guided by relevant standards such as those of the USP and Ph. Eur. and cGLP, allowing us to maintain rigorous quality control, ensuring the material meets our specifications for identity, purity and composition.
METICULOUS EXTRACT PREPARATION
Hawaii Pharm determines the optimal herb-to-menstruum ratio for each botanical. For alcohol-based extracts, we use a carefully balanced alcohol blend to ensure maximum extraction of active compounds while preserving the plant's natural integrity.
Our master herbalists analyze each batch and adjust extraction parameters as needed, ensuring consistent quality despite natural variations in botanical sources.
The result is a potent, stable liquid extract that captures the full spectrum of the botanical's benefits.
COMPREHENSIVE LABORATORY TESTING
Every batch undergoes multiple quality assurance tests including:
  • Organoleptic evaluation (color, consistency, aroma)
  • FTIR and/or HPTLC spectral analysis for identity confirmation
  • Microbiological testing (total plate count, E. coli, coliforms)
  • Yeast and mold screening
  • Alcohol content verification
  • Viscosity measurement
  • Refractometric analysis
