I have fennel in my garden. It doesn’t produce big bulbs, for whatever reason, but it gives me seeds, which I use for my Tummy Tamer tea. Even though I’m in zone 5, plants have come back the next year, and some come up from seeds that fall to the ground.

Cascara sagrada

  • Very bitter, cold, astringent, drying


It appears Gentian is not all that easy to grow. Given that I am all about wild gardening – I plant ’em, then they are on their own – I don’t think I’ll be growing this plant anytime soon. Also, this plant has been over-harvested in the wild so I will be sure to only buy root from cultivated plants, should I want to add it to my herbal closet.

I do not have access to turkey rhubarb, but when we were splitting up a 15-yr old garden rhubarb, I dried some of the root. According to A Modern Herbal, it is similar in action to Turkey Rhubarb, only milder. I haven’t used it yet, it sits in my pantry.

This is another plant listed for reproductive issues in my herbal studies, but when I researched, only A Modern Herbal mentioned it as one of the best herb for lactation. And The Way of Herbs says since abnormal periods are usually accompanied by liver issues, so it is typically added to reproductive formulas. Seems like one of the major use for this herb outside of lactation is as an appetite stimulant.

Also, other thistles, particularly milk thistle, have similar actions.

PS The actions listed are all the ones mentioned across my sources. There are a lot of them!

Mugwort was used in many interesting ways by other cultures. The Chinese use it as part of a technique called moxabustion, where the herb is placed on acupuncture points and burned down to the skin. The Native Americans use the dry leaves for smudging.


Botanical Name: Mentha spicata Family: Labiatae

Common name(s): Spearmint

Spearmint (and all members of the mint family) has the same medicinal properties as Peppermint. Please refer to that materia medica. Spearmint is milder, however, so may be more appropriate for children.

I have found spearmint to be a delightful addition to tea blends, with its milder flavor.

Peppermint will spread! I just learned from Rosemary Gladstar’s book that you should keep your different types of mint separate because they will intermingle and you will wind up with all kinds of mutt mints and they won’t be as medicinal. I have a mint bed with multiple mints. I’ll be changing that up this year!

You can grow peppermint in pots to keep it from spreading, but I’ve found that in my zone 5 climate, it doesn’t always come back the next year when grown in a pot.

One of my favorite things to do in the summer is put a sprig of peppermint – bruising the leaves by twisting them – into a pitcher of water in the refrigerator. So refreshing!

I use horseradish in the fire cider (I call it “Flu Shot”) I make. So I’ve added it to my garden, to have an available supply of organic horseradish. I grate the whole root and store the extra in the freezer.

The root is the part of ginger that is used, but I wanted to include a picture of the aerial parts of the plant, which is beautiful. It can be grown as a houseplant where I live (zone 5).
