A Step-by-Step Guide to Harvesting Mimosa Bark for Medicinal Use

The mimosa tree, also known as the silk tree, is a beautiful ornamental plant native to Asia. It produces lovely pink, pom pom-shaped flowers that have a delicate, sweet scent. But beyond its ornamental virtues, the bark of the mimosa tree has been used for centuries in traditional Chinese medicine.

Mimosa bark contains beneficial plant compounds and has anti-inflammatory analgesic and antioxidant properties. It has been used to treat wounds, muscle pain, headaches, insomnia, and stress. Today, mimosa bark is growing in popularity in the Western herbal medicine tradition.

If you have access to a mimosa tree, harvesting some of its bark can allow you to make your own mimosa bark remedies at home. Here is a step-by-step guide to sustainably harvesting mimosa bark.

When to Harvest

The best time to harvest mimosa bark is in early spring right before the tree leafs out. This is when the bark is most pliable and easy to peel. Avoid harvesting during the heat of summer or when the tree is stressed.

Selecting Branches

When you harvest, you want to hurt the tree as little as possible. For the mimosa tree, look for small, pencil-sized shoots and branches that can be cut back without hurting its shape or health.

Use clean sterilized pruning shears to cut off selected small branches and shoots. Make cuts at a 45 degree angle right above a node or bud. Take only a few branches from each large limb and avoid overharvesting from one area.

Peeling the Bark

Once branches have been cut, the next step is peeling off the outer bark. You want thin, papery strips of the exterior bark. The inner bark is too moist and flexible to use.

Hold the cut end of the branch securely on a hard surface. Take a sharp paring knife and slice down the length of the branch to shave off long strips of the outer bark. Apply minimal pressure so you only remove the papery layers.

Rotate the branch as needed to peel off strips around the entire circumference. The goal is to harvest as much of the useful outer bark as possible without cutting too deep into the inner bark.

Drying the Bark

Freshly peeled mimosa bark needs to be dried before it can be used for herbal preparations. Here are two options for drying:

Air Drying

• Cut peeled bark strips into 1-2 inch pieces
• Lay pieces out in a single layer on mesh screens or baking sheets
• Place in a warm, dry, well-ventilated area out of direct sunlight
• Allow to dry for 1-2 weeks until thoroughly brittle and dry

Oven Drying

• Cut peeled bark strips into 1-2 inch pieces
• Arrange in a single layer on a baking sheet
• Place in oven on lowest setting, 170°F or below
• Dry for 6-12 hours, checking frequently
• Remove immediately once dry and brittle

The slower the drying process, the better it preserves the aromatic compounds in mimosa bark. Store fully dried bark in airtight containers out of sunlight until ready to use.

Making Mimosa Remedies

Once you’ve harvested and dried mimosa bark, there are many herbal preparations you can make:

• Tea: Just mix 1 to 2 teaspoons of dried bark pieces with 8 ounces of hot water and let it steep for 15 to 20 minutes. Strain and drink.

• Tincture: Add bark to vodka or another clear liquor and let it soak for 4 to 6 weeks. Then strain it and put it in amber dropper bottles.

• Powder: To use in capsules, use a coffee or spice grinder to turn dried bark into a fine powder.

• Wash or compress – Make a strong tea and apply externally to skin as a wash, or soak cloth in tea and apply as a compress.

Always properly identify any tree before harvesting. Only harvest from trees you have permission to gather from, and never harvest in protected natural areas. By following these simple steps, you can sustainably forage for mimosa bark and experience the benefits of this special tree medicine.
