History/Folklore: Old folklore and witchcraft traditions claim that blackberry leaves help return evil to enemies that sent it while removing evil spirits from your home.

In Great Britain, folklore tradition suggests that blackberries should not be picked after Michaelmas (September 29th) as the devil is said to have claimed them by urinating on them. As the weather is wetter and cooler this time of year molds can set in making the plants toxic and unfit to eat, so in fact, it is a good practice to leave late-harvest berries alone.

The Kiowa-Apache, Cherokee, Chippewa, Ojibwa, Menominee, Delaware, and Iroquois American Indians have all used blackberry teas and decoctions to help treat diarrhea, hemorrhoids, and lung conditions.

Blackberry leaves have been found to help prevent stomach ulcers and can be used as an effective antibiotic to fight the bacteria, Helicobacter pylori, associated with causing such ulcers.

The USDA (US Department of Agriculture) reports that blackberry leaves used in tea have higher antioxidant compounds than berries do.

The tannins in the leaves help fight diarrhea and dysentery. A heaping teaspoon of dried leaves in a cup of boiling water, with a half cup taken per hour, is a recommended dosage for treating diarrhea.

Blackberry leaves can be combined with sage (LINK)leaves to aid digestive difficulties and bloating.

Old English folklore says that passing under an archway of blackberry brambles will cure, or prevent, hernias, ruptures, and pimples. Celtic lore said blackberries were the fruits of faeries and therefore taboo. Early Christian mythology relates blackberries to both Christ and the Devil. Some say the brambles were used to make Christ’s crown of thorns, thus explaining why the berries turn from red to black. Some stories relate that the devil Lucifer landed in a bramble of blackberries when he was cast out of heaven. Still, blackberries were understood to ward off evil, ghosts, and vampires. If they are planted near your home a vampire would not be able to enter, as he would begin to count the berries and forget what he was up to!

The plant’s thorny branches are used for protection. The vines are woven into protective wreaths and the leaves are used to treat all sorts of feminine fertility issues.

The cooked berries are used in spells and cooking to ensure prosperity. Blackberry pies are baked to celebrate First Harvest festivals.

Blackberry is not native to China and is therefore not often used by Chinese herbalists. As it is more easily available in the Americas and Europe, Western healers of TCM (Traditional Chinese Medicine) integrate blackberry into TCM herbal protocols and formulas as needed.

Permanent black dye can be made from blackberry leaves and lye. An orange dye is made using the roots, and a bluish-grey dye is made from the berries.

The leaves should be harvested before or during flowering and the roots are best harvested in the Spring or Fall after the berries have been harvested and dried quickly in an oven or under the hot sun.
