Echinacea is best taken in small frequent doses. If used in the long term only take for six days out of the seven, or three weeks out of the month, to obtain the best effect.

For the gardener

Sow the seeds 1/4 inch deep on a seed raising tray. This can be placed on a warm windowsill in late winter to early spring.

Once the seedlings are established plant them out so they are 6-12 inches (15-30 cm) apart. They prefer full sun though they will tolerate partial shade. Plant them in humus rich well drained soil. This will encourage good root production. The roots are harvested at the second year of growth. Wait until the plants have gone dormant (the leaves will have shrivelled and gone brown) before digging them up.
