Crafting Herbal Infused Oils

Crafting Herbal Infused Oils

Part of the Nature to Nurture Series from Blackcreek Herbals™ & Blackcreek Nursery

INSTRUCTIONS

Herbs have been used for centuries to support health and well-being, not only in teas and tinctures but also in oils. An infused oil is a simple preparation that captures the beneficial qualities of herbs and brings them into everyday life—whether in the form of a soothing balm, a relaxing body oil, or even a practical garden spray.

This article is part of our Nature to Nurture series, where we share approachable ways to use herbs safely, effectively, and with confidence.

What Are Herbal Infused Oils?

Herbal infused oils are made by soaking dried herbs in a carrier oil. Over time, the plant’s beneficial compounds transfer into the oil, creating a preparation that can be used in countless ways. Massage oils, skin moisturizers, scalp treatments, healing salves, lotions, soaps, and even certain culinary creations all begin with this simple process.

Choosing the Right Herbs

When making herbal oils, safety and intention matter.

Fresh vs. Dry:
Fresh herbs contain water, which increases the risk of spoilage, rancidity, or even botulism. For this reason, dried herbs are always the preferred choice for infusions.

Topical vs. Culinary:
Culinary oils made with dried herbs like rosemary or oregano can be delicious, but they must be handled carefully. They should always be refrigerated and used quickly to avoid the risk of mold or bacterial growth.

The best approach is to select herbs based on your intended use. Always research their benefits, be aware of cautions, and consult with a healthcare provider if you have any concerns or medical conditions.

Carrier Oils and Shelf Life

The choice of carrier oil influences both the shelf life and the character of your infusion:

  • Olive oil – nourishing, ~12 months
  • Almond oil – light, 6–9 months
  • Coconut oil – protective, 1–2 years
  • Jojoba oil – very stable, 2+ years
  • Grapeseed oil – quick absorption, ~6 months
  • Sunflower oil – 6–12 months (high oleic preferred)
  • Avocado oil – moisturizing, ~12 months

Adding a small amount of Vitamin E oil (about 1% of the volume) can help extend freshness for topical uses.

Storage and Spoilage Signs

Herbal oils made with dried herbs will last as long as the carrier oil itself if stored well. Keep jars in a cool, dark place, and consider refrigeration for extra protection.

Signs of spoilage include:

  • Off odors (paint, crayon, rancid nuts)
  • Visible mold
  • Cloudiness or unusual color

When in doubt—throw it out.

Ratios and Infusion Methods

There are two approaches to measuring herbs for oils:

  • Ratio Method: 1 oz dried herb to 8–10 oz oil (Blackcreek  preferred method)
  • Folk Method: Fill a jar halfway to three-quarters with dried herbs, then cover with oil

Infusion methods include:

  • Sunny windowsill: 2–4 weeks, shaken daily
  • Dark shelf: 2–4 weeks, shaken daily
  • Crockpot water bath: 2–12 hours at 100–140°F (never above 150°F)

Always sterilize jars before use, let them dry completely, and label each one with the herb, oil, and date.

Suggested Herbal Blends

Here are a few simple combinations to inspire your own creations:

Joint Ease Oil – calendula, plantain, turmeric: soothing and anti-inflammatory

Calming Body Oil – lavender, lemon balm, chamomile: relaxing after-bath care

First Aid Oil – calendula, yarrow, plantain: quick care for bites, stings, and scratches

Balms and Salves

  • Infused oils are the base for two classic herbal remedies: salves and balms.
  • Salves are softer, absorb quickly, and are best for skin healing.
  • Balms are firmer, last longer, and often include butters for added protection.
