What the evidence says

The historical record and practitioner context are meaningful evidence lanes. Modern human research varies by topic and preparation and is presented separately; lack of modern study is not proof that a tradition has no value.

Traditional and practitioner context

Flax is one of the oldest cultivated fiber and food plants. The seed, traditionally called linseed in herbal contexts, has been eaten whole or ground and prepared as a mucilaginous drink or poultice in European, Middle Eastern and South Asian traditions.

Safety note

Know before you use it

Take ground flax with adequate fluid and introduce fiber gradually. Flax oil does not provide the seed’s fiber. Discuss concentrated use with a clinician if medicines, pregnancy, swallowing difficulty or bowel narrowing are relevant.
