## Mathmetical medical measurements

I’m actually writing this post because I will NOT retain this in my head. I do not retain anything numerical. I am a word person (like that alliteration I put right there in the title of this post).

This is some general information I found about dosage equivalents for liquid (extracts/tinctures) and powdered herbs.

First up, 1 ml and 1 cc are equivalent. I’m going to refer to ml, but you could substitute cc, if you are using a measured dropper.

Also, a drop is an approximation, as is a dropperful. But, generally:

1 dropperful = 30 drops extract = 1 softgel

1 drop = 25 mg of ground herbs = .04 ml, which means there are 20 drops per ml which is equivalent to 500 mg ground herbs

Bonus info. There are approximately 40 dropperfuls (1,200 drops) in a one ounce bottle of herbal extract.

Okay, taking out the extra words:

• 0.4ml/drop = 25 mg powder
• 20 drops/ml = 500 mg powder
• 30 drops/dropperful
• 30 drops/softgel
• 40 dropperfuls/1 ounce bottle = 1,200 drops/1 ounce bottle

## My witch hazel experiment

Last year I went to 3 wildcrafting classes with Emily French of Sweetgrass Herbals. At one of them she introduced us to witch hazel. I harvested a few leaves, then went to look for trees on my property, down by the stream. I found a few! So I picked a couple more leaves. And made a small tincture of them using alcohol. Later that year, as I was hiking the mountain, I noticed that part of the trail was lined with witch hazel. Tons and tons of it. I filed that knowledge away for the future.

Fast forward to this year. Early spring, as I hiked the trail, I looked for the trees. The leaves were only budding so I couldn’t be sure. (The way to identify witch hazel is that the base of the leaf is asymmetrical where it connects to the branch. Some of the leaves are also kind-of rounded on the other end, although not all of them. The base of the leaf is a better indicator. The trees also are not tall trees, and I’d call them kind of leggy-looking.) These are them:

Two weeks later, the leaves were out and I spent some time gathering them (as you can see, I hiked after a rain shower), a few from each tree, giving thanks for the medicine as I harvested. When I got home I put them into a jar with rubbing alcohol, after reading about that as menstruum for a liniment in my herbal studies. I figured it would be a good comparison to the other tincture I made.

Here are the results:

It’s hard to tell, but the one on the left is VERY green. The rubbing alcohol pulled every bit of green out of those leaves. The one on the right pulled color – it was plain clear vodka to start – but not nearly as much. I tried them both on an itchy patch of skin. The one on the left worked better, too. I do have to say that it smells awful though. Not anything like the witch hazel you get from the drug store. It smells like rubbing alcohol.

Speaking of that, why is the witch hazel you buy clear? I don’t intend to use the store-bought one in the future. Not if I can buy a bottle of rubbing alcohol for as cheap as a bottle of witch hazel, pick free leaves infused with the energy of thankfulness, and just combine the two for several weeks. In fact, I intend to make another batch or two this summer to have enough to get through the winter until the leaves bud again in the circle of the seasons.

I love making my own medicine!
