How to Make a Soothing Calendula Poultice

The specific herbs used in soothing herbal poultices will affect the exact medicinal properties of each poultice.

Soothing herbal poultices are simple, traditional remedies used topically on the skin to relieve pain, infection, and swelling. They are water-based, which makes them especially choice when oil-based remedies (that hold in moisture and heat) are contraindicated. Herbal oils and salves shouldn’t be applied to weepy skin conditions or bacterial and fungal skin infections because they can hold in moisture and reduce airflow. Additionally, I find that herbal poultices are often more effective topical remedies than oil-based herbal preparations, simply because poultices are more concentrated, as they contain plenty of fresh herbal material.

In general, herbal poultices are beneficial for poison ivy rashes, weepy eczema, hives, insect bites, psoriasis, pimples, boils, fresh sunburns, and fungal and bacterial skin infections. The specific herbs used affect the exact medicinal properties of each poultice.

Poultices are prepared by blending therapeutic plants (fresh or dried) into a green slurry or paste, after which they are applied directly to an afflicted area. The slurry is then covered with a clean, dry cloth or bandaging material, depending on the size of the area being treated. Adding a binder such as clay makes the poultice easier to apply and helps it stay put. Clay has its own skin-healing benefits as well and is especially helpful for drying weepy skin conditions such as poison ivy.

As you might surmise, poultices can be a messy business.

A tamer version involves wrapping the moistened herbal material into a loose-weave, permeable cloth and placing it on the area to be treated. The most primitive version of a poultice is the aptly named chew and spit poultice, which is applied, as you might imagine, solely on one’s own body.

Below, you’ll find one of my favorite soothing herbal poultice recipes. Take note that this recipe uses fresh herbs. If you’re working with dried herbs, bring a small amount of water to a boil, turn off the heat, and add a sufficient amount of the dried herbs until the herbs rehydrate and form a thick paste. Stir and let cool for comfort of application.

This cooling and moistening poultice is helpful for dry, irritated skin conditions such as psoriasis, rashes, chicken pox, and chafed skin. It can also be used to soothe insect bites, mild abrasions, cuts, and scrapes. The combination of herbs provides a soothing blend of healing properties that are demulcent, anti-inflammatory, and vulnerary (wound-healing).

    I am loving your articles and currently trying to save the money to enroll in your classes. I was wondering what clay and where you can get it from? Thank you!

    • Christine Borosh says:

      Any powdered pure cosmetic clay will work. Bentonite clay is probably what you’ll most commonly find, but there are many other options you may come across as well. Powdered clay can be purchased from health food stores or online through companies like Mountain Rose Herbs or Starwest Botanicals.

      We’re looking forward to having you join us as a student when the time is right!

    • Sarah Sorci says:

      Bentonite clay is typically what I use for topical preparations, and I find it works great! I hope you enjoy this poultice recipe 🙂

    Hello! I am joining your school. On your blog about calendula oil. I made mine differently before I consulted your school. I put my dried flowers , sunflower oil. Put the jar in the dark in my closet. (3 weeks) is it too late to blend it?

    • Sarah Sorci says:

      It’s wonderful to hear that you’ll be joining us as a student, Marie!

      I don’t see any reason not to blenderize your herbs and oil after a few weeks of macerating in the closet, if you didn’t do so beforehand. I hope you’re pleased with the final product!
