Buckwheat is a fantastic phlebotonic (vein tonic) due to high content of rutin.



Other names


Botanic characteristics

It grows from 15 to 60 cm tall (6 to 23 inches).


A very easy to grow medicinal plant, buckwheat grows well is poor soils, especially sandy soils. Seed directly on a sunny area and make sure no other plants will shade it during the growing season. It needs as much sun as it can get to develop enough rutin.


For medicinal purposes, harvest buckwheat herb 8 weeks after germination in the afternoon when the flowers begin to bloom. The seeds (fruits) are ripe 2-3 months after germination and not all ripen at the same time. So, plan for several harvests.


Spread the herb on a flat surface and dry it fast. I use a dehydrator. Store it in an air-tight container.


4-8% flavonoids (90% rutin but also hyperoside), quercitrin, phenolic carboxylic acid (chlorogenic acid, gallic acid, salicylic acid), traces of the photo-toxic napthodianthrone fagopyrin and small amounts of fagopyrin, anthocyanins and plant acids.

Note: Fagopyrin can cause photosensitivity but since it isn’t water or fat soluble (it doesn’t release into water or fat), it very safe to consume as infusion.


Phlebotonic, anti-sclerotic, anti-hemorrhagic, antioxidant
