Kanpo (herbal medicine)
The
Japanese herbal medicine tradition developed originally from Chinese texts but,
like many of the therapies described earlier in this chapter, went through
uniquely Japanese stages of refinement and development. Nowadays, in Japan,
only medical doctors are legally allowed to practise kanpo, yet over the counter kanpo
remedies for the general public are hugely popular.
Japanese
formula generally use fewer herbs than the Chinese ones and dried granular
extracts are more commonly used than fresh herbal ingredients because they’re
convenient and easy to take.
Kanpo diagnosis is based on eight
principles described below as four pairs of opposites:
1.
Determining
if the person’s symptoms are predominantly kyo
(deficient) or jitsu (excess)
2.
Determining
the stage of illness (chronic/acute)
3.
Ascertaining
whether the disease is external and superficial or internal and deep
4.
Determining
whether symptoms are predominantly hot or cold
After
the predominant underlying weakness, or kyo,
has been identified, it can then be treated with appropriate medicinal herbs.
This approach is almost the opposite to the Western medical one, which focuses
on identifying and treating the invading germ, virus, or bacteria. In kanpo, the emphasis is on supporting the
weak or vulnerable parts or systems of the body to prevent them from succumbing
to invading pathogens.
Because
kanpo medicine focuses on an
individual’s constitution and that person’s particular response to the disease,
the treatment for different people with the same disease, according to Western
medicine, will often be different. So, for example, if five people were
diagnosed with asthma, in Western medicine they may all be prescribed the same
type of inhalant medication, yet, in kanpo,
their herbal medicine prescriptions, while maybe having some ingredients in
common, would probably all differ.
Most
kanpo formulas have five to ten
ingredients. They’re usually made from plant ingredients including roots, bark,
leaves, flowers, fruit, and fungi, although occasionally mineral or animal
ingredients may be used. These ingredients are selected according to their
individual effects on the body and also their combined effects with each other.
Kanpo herbal medicines are well
researched and are regarded as safe to take, with virtually no side effects if
prescribed and taken properly. If you’re pregnant, breast-feeding, or hoping to
conceive you must always inform your practitioner or consult your GP before
taking kanpo medicinal herbs.
You
can take kanpo herbal medicines with
Western medicine but ensure you’re carefully monitored by qualified and
experienced practitioners in case of interactions. Always inform your GP and
herbal practitioner of any medicines and herbs that you’re taking.
