Most of the time, herbs are measured in drops for liquid
extracts and cups for teas.Capsules are another popular choice, but I don't cover them here
because, although empty capsules can be filled at home, they have to be
manufactured elsewhere. Extracts, on the other hand, can be made at home from
start to finish with homemade fruit-based alcohol or apple cider vinegar.
Herbal teas can also be grown at home from seed to harvest, so we will look at
those as well.
To determine how much of an herb to give, first determine
whether or not it is considered safe for normal use or if it is a low dose
botanical. A low dose botanical is an herb that has a traditional record of use
in small quantities, but may or may not be considered safe according to modern
research. Lobelia is one example. It is potentially toxic and can induce
vomiting in large doses, but in small doses was traditionally used as an
effective lung support herb for asthma. Normal herbs are given in 15-30 drop
quantities, while the dose for lobelia was traditionally started at 5 drops.
This is where it is important to have several good books on hand when you are
becoming acquainted with a new herb, and it also pays to look up the herb in a
more historical work as well. At least one of your reference books should be
written by a fairly technical herbalist who likes to go into nitty gritty
details such as dosage rather than simply leaving it to be implied. One
excellent resource for this is Michael Tierra's book, Planetary Herbology,
which briefly covers hundreds of herbs from several traditions around the
world.
As stated above, most herbal extracts are given in 15-30
drop quantities. This is usually assuming a body weight of 150 lbs, or one to
two drops per ten lbs of body weight. One drop per ten lbs is a good place to
start for children, and it can be increased to two if needed.
It's been my experience that homemade extracts can have
higher levels of sediment than store bought ones, so I'm not really a fan of
storing my extracts with dropper top bottles. I use screw on caps but keep
clean droppers stored separately- the droppers are convenient, just not when
they clog repeatedly. Which they will do, especially on extracts you don't use
everyday.
So, either store the dropper separately, or learn to use a quarter teaspoon measuring spoon. 1/4 teaspoon of extract equals roughly 30 drops. By adding the
extract to a small amount of water and dividing the water in half, you will
have approximately 15 drops, and in half again will yield about seven.
Frequency of use is another consideration. If you know that
the herb you are planning to use falls under the category of normal use, next
consider what type of problem you are addressing.
If it is an acute imbalance, such as a cold or something
else that comes on suddenly, herbs can be taken every hour as needed for a few
days. If the imbalance is chronic- something that has been around for months or
years, it is generally best to use the herbs two or three times a day, and
expect that they will need to be continued for one month to every year the
imbalance has been experienced.
