Dosage

Infusion: pour a cup of boiling water onto 1/2 to 1 teaspoonful of the powdered herb and leave to infuse for 10 - 15 minutes. This should be drunk three times per day.

Tincture: take 2-4 ml of the tincture three times per day.

For the gardener

After years of over harvesting golden seal has become an endangered species.

The plant can be grown from seed but it takes up to 5 years for the roots to be mature enough to gather.

Keep fresh seeds in moist but not water logged soil, so they can continue to develop (stratify) for 3 months. If you do this in seed trays you should have seedlings by spring. Allow them to grow until the autumn of the second year, then separate them and then plant them out 6 inches (15cm) apart.

You can purchase a two year old dormant root division. Plant these 12 inches (30 cm) apart.

They need a deep rich loamy soil and a mulch of well rotted leaves. Water occasionally to keep the soil moist but not soggy.

Harvest the roots in the autumn, when the tops die back. Save the biggest roots for replanting.
