This week we’re sharing a formula for an herbal cold sore remedy – a soft salve or balm that can be applied right on the sores. It’s going to serve as a jumping-off point for discussing flexible formulation. That’s the answer to the question “what can I do if I don’t have one – or any! – of the herbs in the formula as written?” If you can answer this question, you’ll be much more adaptable when you run out of herbs or when you’re away from your home apothecary.We start out with the formula we published in our book Herbal Medicine for Beginners, then we break it down from the perspective of herbal actions. After identifying the herbs that contribute vulnerary, antimicrobial, lymphatic, and nervine actions to the remedy, we can come up with substitutions that would fill similar roles.Here’s the formula as we presented it in our book, for comparison:Cold Sore BalmMakes 5 ounces (about a 3-month supply)This gentle salve is very soothing to irritated cold sores, and helps reduce inflammation while making your body’s environment less hospitable to the virus.1 fluid ounce calendula-infused oil1 fluid ounce plantain-infused oil½ fluid ounce self-heal-infused oil½ fluid ounce chamomile-infused oil½ fluid ounce st john’s wort-infused oil½ fluid ounce thyme-infused oil1 ounce beeswax, plus more as needed1. Combine the oils in a pot and warm them over low heat.2. Add the beeswax and stir continuously until it melts. 3. Spoon some of the melted oil & wax into a shotglass and place it in the freezer for a few minutes; it will set to its finished hardness. Take it out and test it with your finger to see if it is the consistency you want.4. Add more wax if you want to harden your salve; add more oil if you want to soften it.5. Pour into a short, wide-mouth jar (or fill lip balm tubes), then cover and allow to cool/set.6. Apply liberally to the affected area, 3 to 5 times daily.Herbs discussed include: calendula, plantain, chamomile, thyme, self-heal, st john’s wort, lemon balm, common bugle, red clover, pine, damiana, violet, goldenrod, oregano, rosemary, lavender.Mentioned in this episode:Herbal Medicine for Beginners – This is our book!
