It is this combination of nutrients that makes burdock such a popular herbal remedy.

The polysaccharides found in burdock root and leaves are regarded as beneficial to human health because of two main reasons: its action as a diuretic and as a blood-purifying agent.

Burdock grows wild throughout the world with little to no assistance, making it incredibly easy to grow. However, in the case of burdock, the more attention you pay to this plant, the more it will thrive, growing deeper roots.
For best results, growing it directly from the seed is recommended, since it will produce the highest germination rates.
If sown under cold climate conditions or during the fall season, burdock seeds yield best results if planted under one inch (2.5 cm) of soil, although during springtime only half an inch is usually necessary.
It is best if burdock is grown in a place with full sun, in well-drained and fertile soil, which should be cleared of stones and rocks to allow roots to develop.
Ideally, burdock should be planted in rows with an optimum spacing of six inches (15 cm) between each plant.
Soil must be kept moisturized for best results, and the use of fertilizers is recommended in order to accelerate its growth.
Roots should be harvested when they are approximately one inch (2.5 cm) thick and 10 inches (25 cm) deep. Fruits should be harvested only when already ripe.
Flowers and burrs should be continuously picked to promote new growth.
