Cut a few thin slices of fresh rhizome and steep in hot water (not boiling) for about ten minutes. Strain and drink warm, possibly sweetened with honey. One to two fresh slices (approximately 1 to 2 g) per cup, up to 2 to 3 cups per day.
Gently boil pieces of dried rhizome in water for about fifteen minutes, then let steep before straining. This more concentrated preparation was reserved for occasional use. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.
Macerate grated fresh rhizome in a neutral vegetable oil for several days away from light, then strain. This oil was applied in local massage on joints, avoiding sensitive or damaged areas. Dosage should be validated with a healthcare professional or recognized pharmacopoeia before use.
Fresh ginger can be found in grocery stores and markets, and in dried or powdered form at herbalists and specialty food stores; it can also be grown in pots in temperate regions with a bit of warmth.
The rhizome is traditionally harvested at the end of the growing season, when the leaves turn yellow, generally several months after planting.
