|Catnip in early spring|
Most medicinal plants are preserved after harvest by drying for infusion or tincturing. A few garden mints, however, are more effective if used right after picking.
|Lemon balm in mid-spring|
HERBALIST'S NOTE: Tincturing of fresh plants can be done by the folk method (chop into jar, cover with alcohol) as shown for lemon balm, the weight-to-volume method (1:2 ratio of plant to alcohol in blender) as for basil, or a combination as for catnip since it took 5 parts alcohol to cover 1 part of the plant.
