Read before use: the information below describes traditional and informational uses — it does not replace the advice of a healthcare professional. In case of doubt, pregnancy, breastfeeding, ongoing treatment, or use in children, seek advice before use.
Enhanced precautions for this plant: Always accompany the intake of flaxseeds with sufficient water, due to their strong swelling capacity, to avoid any digestive discomfort. Not recommended in case of known intestinal obstruction or narrowing; seek advice from a healthcare professional if in doubt. Flaxseed has mild estrogenic activity: regular use should be discussed with a professional in case of pregnancy, breastfeeding, or hormonal treatment. Whole seeds that are not ground and not well moistened may pass through the digestive system without releasing their benefits; prefer freshly ground seeds.
Infusion / cold maceration — Whole or crushed seeds
Flaxseed mucilage
Soak the seeds for several hours in cold water until a thick, mucilaginous liquid is obtained. This mucilage was traditionally drunk or used as a gargle to soothe mucous membranes. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
Poultice — Ground seeds
Flaxseed poultice
Grind the seeds then mix them with hot water until a smooth paste is obtained. Apply warm to the concerned area, wrapped in a thin cloth, avoiding any contact with broken skin. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
Infused oil / cold-pressed — Seeds
Traditional flaxseed oil
The oil obtained by cold pressing the seeds was kept cool and consumed raw in small quantities, never heated, as it deteriorates rapidly when exposed to light and heat. Dosage must be validated with a healthcare professional or recognized pharmacopoeia before use.
