Dosages
- generally speaking children aged 7 - 12 years
should be given no more than half an average adult
dose. For children aged 1 - 6 years use a third
of an adult dose, and for babies aged 6 - 12 months
only a tenth of an adult dose. Much depends on the
child's size and general health conditions but as
a rough guide Penelope
Ody suggests the following dosages : 1 - 2 years
= 10% of adult dose; 3 - 4 years = 20% of adult
dose; 5 - 6 years = 30% of adult dose; 7 - 8 years
= 40% of adult dose; 9 - 10 years = 50% of adult
dose; 11 - 12 years = 60% of adult dose; 13 - 14
years = 80% of adult dose; 15 plus = 100% of adult
dose;
Always
research the herbs you wish to use - not all are
suitable for children. The following herbs, however,
are all gentle, safe healers and some of the most
commonly used herbs for young children : German
Chamomile - Chamomilla recutita; Marigold - Calendula officinalis; Catnip - Nepeta
cataria; Lemon Balm - Melissa officinalis
