All Herbs Are Not Equal

All herbs are not equal: some contain poisons, some don't; some of the poisons are not so bad, some can kill you dead. I divide herbs into four categories for ease in remembering how (and how much) to use. Some herbs nourish us, some tonify; some bring us up or ease us down and some are frighteningly strong.

Nourishing herbs are the safest of all herbs. They contain few or no alkaloids, glycosides, resins, or essential oils (poisons).

Nourishing herbs are eaten as foods, cooked into soups, dried and infused, or, occasionally, made into vinegars.. They provide high-level nutrients, including vitamins, minerals, trace minerals, proteins, phytoestrogens and phytosterols, starches, simple and complex sugars, bioflavonoids, carotenes, and essential fatty acids (EFAs).

Nourishing herbs in water bases (infusions, soups, vinegars) may generally be taken in any quantity for any period of time. Side- effects -- even from excessive use -- are quite rare. Nourishing herbs are rarely used as tinctures (in alcohol), but when they are, their effects may be quite different.

It is generally considered safe to use nourishing herbs in water bases with prescription drugs. They may also be taken even if you are using tonifying, stimulating/sedating, or potentially poisonous herbs.

Some examples of nourishing herbs include:

burdock roots
chickweed herb; tincture dissolves cysts
comfrey leaf
elder blossoms and berries
mushrooms
nettle leaves and seeds
oatstraw
plantain leaves and seeds
red clover blossoms
seaweeds
violet leaves and blossoms.

Tonifying herbs are generally considered safe when used in moderation. They may contain alkaloids or glycosides or essential oils, but rarely in quantities sufficient to harm us.

Tonifying herbs act slowly in the body and have a cumulative, rather than immediate, effect. They are most beneficial when used for extended periods of time. Tonifying herbs may be used regularly (but usually not daily) for decades if desired.

Tonifying herbs are prepared in water and alcohol bases: tinctures and wines, as well as infusions, vinegars, and soups.

The more bitter the tonic tastes, the less you need to take of it. The more bland the tonic tastes, the more you can use of it.

Side effects from overuse and misuse of tonics is uncommon but quite possible. The dividing line between what is tonifying and what is stimulating differs from person to person. Ginseng is tonifying to my sweetheart, but stimulating to me. Even herbal authorities disagree on
which herbs are tonifying and which stimulating.

Take care to counter any tendency to overuse tonifying herbs or you may experience unwanted side effects.

It is generally considered safe to use tonifying herbs in water bases if you are taking prescription drugs. You may also use tonifying herbs while using nourishing, stimulating/sedating, and even potentially poisonous herbs. Tonifying herbs in alcohol bases are considered safe to use with nourishing herbs, but may produce unexpected results if combined with drugs or strong herbs.

Some examples of tonifying herbs include

burdock seeds, especially in an oil base
chasteberry
mug/cronewort herb, especially in vinegar
dandelion leaf, root and flowers
Echinacea root
ginseng root
hawthorn berries, leaves, and flowers
horsetail herb
motherwort leaves and flowers
yellow dock leaves, roots, and seeds

Stimulating/sedating herbs frequently contain essential oils, alkaloids, glycosides, or resins. Because these substances cause strong physical reactions, stimulating/sedating herbs are known from their rapid and pronounced effects, some of which may be unwanted.

Stimulating/sedating herbs are most often prepared as tinctures (and wines), vinegars, teas, and infusions. Many stimulating/sedating herbs are used as seasonings in cooking as well. Despite my cookbook's injunction to use only a little, I long ago learned that more aromatic herbs in my soups gave a "livelier" result.

Because long-term use of stimulating/sedating herbs can lead to dependency, dose and duration of use must be carefully watched. A moderate to large dose, taken infrequently will produce better results than a small dose taken over a longer period.

Side effects from the use of stimulating/sedating herbs in water bases are not common but possible. Side effects from use in alcohol bases are frequent. Whenever stimulating/sedating herbs are used regularly, health is compromised.

It is not safe to take prescription drugs with stimulating/sedating herbs, but they may be taken even if you are using nourishing and/or tonifying herbs.

Some examples of stimulating/sedating herbs include:

leaves of aromatic mints such as catnip, lemon balm, lavender, sage, skullcap
cinnamon bark
coffee beans
ginger root
kava kava root
licorice root
tobacco leaves
uva ursi leaves
valerian root
willow bark and leaves

Potentially poisonous herbs always contain alkaloids, glycosides, resins, or essential oils. And they contain large quantities of those poisons, or in very potent forms.

Potentially poisonous plants can cause death directly, through the actions of their poisons on their targets (such as cardiac glycosides which stop the heart) or indirectly, by causing the liver and/or the kidneys to fail (as they attempt to cope with and clear the poison from the system).

Potentially poisonous herbs are usually extracted into alcohol (tinctures) and used in minute doses (1-3 drops). For safety sake use potentially poisonous herbs as infrequently as possible and for the shortest possible time.

Powdering and encapsulating increases the risk of side effects from any herb, but when we take stimulating/sedating and potentially poisonous herbs in capsuled, the side effects can be deadly.
Homeopathic pharmacy uses many potentially poisonous plants, but in such dilute doses that death is impossible. Side effects can occur, even with homeopathically tiny doses, however.

Potentially poisonous herbs activate intense effort on the part of the body and spirit and may cause nausea, visual disturbances, digestive woes, and allergic reactions even when used correctly.

Always be extremely cautious when using potentially poisonous herbs. Consult with at least three other knowledgeable herbalists who have used the plant in question before proceeding.

In general it is not considered safe to take potentially poisonous herbs which taking prescription drugs, other potentially poisonous herbs, or stimulating/sedating herbs. It is generally safe to use potentially poisonous herbs while using nourishing and tonifying herbs.

Some potentially poisonous herbs:

belladonna
castor beans
cayenne
cotton root
goldenseal
liferoot/groundsel
nutmeg
poke root
tansy leaves and flowers
wormwood.
