Fagopyrum

Made from buckwheat — the triangular seed of the high fields, its fagopyrin a genuine photosensitising chemistry, and the classical remedy of the itchy, prickling eczema.

The whole picture, in one breath

Think of an itch that prickles beyond the rash: the eczema of the books with the peculiar prickling, itching worse for scratching, the blotched skin, and the triangular seed of the high fields. The prickling-itch seed: that is Fagopyrum.

The substance, in plain words

Buckwheat is the triangular seed of the high fields, its dark hulls carrying fagopyrin — a genuinely photosensitising chemistry documented in livestock as fagopyrism, the real toxicology of the grain's overuse. The proving gave the seed the prickling-itch portrait.

Where the classical picture comes from

The high-field seed's proving gave the prickling-itch portrait; Fagopyrum became the classical remedy of the eczema that prickles — the triangular grain serving the itch its own chemistry mirrors.

The substance in real medicine Pharmacology

What this section is: the pharmacology and toxicology of the source substance. It is not clinical evidence that a homeopathic preparation of it treats any condition. What controlled trials do and do not show is set out on the Evidence page.

Buckwheat's fagopyrin is genuinely photosensitising — the documented fagopyrism of livestock fed too much buckwheat, a real, studied toxicology of the grain. The eczema it portrayed is now dermatology's; the seed's chemistry is real, its modern career the pancake and the soba noodle.

Look-alikes (how the classical authors told it apart)

RemedyLooks similar because…Tells it apart because…
Dolichos pruriensItching without eruptionDolichos' is the hepatic itch with nothing to show; Fagopyrum's the prickling eczema with the blotch.
SulphurItchy hot skinSulphur is hot, red and bath-hating; Fagopyrum is the prickling, scratch-worse one.
PsorinumOffensive chronic itchPsorinum is filthy, freezing and despairing; Fagopyrum the prickling grain chapter.
MezereumBurning under crustsMezereum burns under the chalky crust; Fagopyrum prickles on the surface.
Safety. Persistent or worsening eczema needs dermatological assessment — the skin is examined, not scratched.
