Introduction to Herbal Oils
Herbalism is a fascinating and vast world. . . and, at times, intimidating! Making tinctures using the percolation method or making your own mead can seem daunting to those new to the botanical arts. That’s why, when we’re trying to help a friend get started in herbs without overwhelming them, one of our favourite herbalism projects for beginners is making herb-infused oils.
Simply infusing a carrier oil with herbs makes it a versatile ingredient. There are several methods for infusing oils, but our favourite is the “folk” or “simplers” method, which relies on the sun to naturally infuse oil with herbal properties.
Many different organic carrier oils can be used, but fractionated (MCT) coconut oil and olive oil are popular and wise choices due to their long shelf lives and suitability for a wide range of applications. Herbal oils can be used to make marinades, massage oils, salves, lip balms, facial serums, hair treatments, body creams, soaps, and a variety of other products.
-
- While most herbs can be infused either dried or fresh (with proper preparation), some are better suited to one than the other. St. John’s wort, for example, is widely thought to require fresh material to produce an effective herbal oil.
-
- Herbal oils can go rancid or mouldy if the carrier oil isn’t very shelf stable (like rosehip seed oil) or if fresh herbs are used. To ensure safety, infused oils that change colour, scent, clarity, or taste should be discarded. Using the alcohol intermediary infusion method or adding a preservative such as vitamin E can help keep oils stable for longer, but it also renders them unfit for consumption.
-
- Herbs containing natural dyes can be infused in oil and used to colour soaps and other body care formulations.
-
- Wear gloves when straining a finished herbal oil through a cheesecloth-lined strainer and squeezing out any remaining oil in the herbs. While you can work with oils with your bare hands, it is a messy process, and certain herbs, such as turmeric, may temporarily stain your hands and jewellery.
-
- Often, the oil will not wash out of cheesecloth or muslin, so strain with something you won’t reuse.
-
- Fine herb sediment can make oil a little gritty even after straining; if this bothers you, strain again through a coffee filter. This is a slow-drip process that may necessitate the use of more than one coffee filter to strain all of the oil.
-
- Herbs can be combined to make synergistic infusions. For example, hops flowers, lavender flowers, and chamomile flowers infused in jojoba oil make a wonderful relaxing massage blend. Mix and match to meet your specific requirements!

Blue Vervain
Blue Vervain Overview
Blue vervain, or Verbena hastata, is a perennial plant in the Verbenaceae family that is native to North America. The plant has tall, slender stems and small clusters of blue or purple flowers, and it is commonly found in damp meadows, along rivers, and in marshy areas.
With a long history of use in traditional medicine, blue vervain is valued for its calming properties and ability to alleviate stress, anxiety, and insomnia. It has also been used to treat menstrual cramps, headaches, and digestive issues.
To obtain its benefits, the aerial parts of the blue vervain plant, including the leaves and flowers, are harvested and dried for use in teas, tinctures, and capsules. The herb has a slightly bitter and earthy flavor, and it is often combined with other herbs to enhance its effects.
Blue vervain is believed to offer a range of health benefits, including supporting healthy digestion and respiratory function, as well as having mild anti-inflammatory and diuretic properties. It is important to note that individuals who are pregnant, nursing, or taking medication should consult with a healthcare professional before using blue vervain or any herbal remedy.
Overall, blue vervain is a versatile and valuable herb that has been used for centuries in traditional medicine. Its calming properties and potential health benefits make it a popular choice for those seeking natural remedies for a variety of ailments.
Growing
&
Harvesting
Planting blue vervain is relatively easy. You can start it from seeds indoors a few weeks before the last frost date, or direct-sow them in the garden. Blue vervain is a hardy plant and has few disease and pest problems.
When handling blue vervain plants, wear gloves and avoid touching your face, as some people may experience skin irritation.
While blue vervain is not typically considered an invasive species, it can spread quickly and become weedy if left unchecked. To prevent this, consider planting it in a contained area, such as a raised bed or large container.
Blue vervain prefers moist soil and can tolerate a range of growing conditions. Water regularly, especially during dry spells, to keep the soil moist. Deadheading spent blooms will encourage the plant to continue producing new flowers and prevent self-seeding.
Harvesting blue vervain regularly can also help control its growth and prevent it from becoming weedy.
Light
Blue vervain prefers full sun but can tolerate some shade, especially in hotter climates.
Soil
This plant prefers well-drained soils and can grow in a range of soil types, including loamy and sandy soils. Blue vervain prefers slightly alkaline soils but can tolerate slightly acidic conditions. Adding organic matter to the soil can help improve fertility and moisture retention. Blue vervain does not tolerate extremely wet or dry soils.
Water
Blue vervain has average water requirements and can tolerate short periods of drought once established. Water regularly during dry spells, especially in hotter climates, to keep the soil evenly moist.
Temperature and Humidity
Blue vervain can grow in a range of climates and is hardy in USDA zones 3 to 9. It prefers moderate to high humidity but can tolerate dry conditions once established.
Fertilizer
Blue vervain does not require frequent fertilization but can benefit from an annual application of compost or a balanced fertilizer. Too much nitrogen can result in lush foliage at the expense of flowers.
Pruning
Deadheading spent flowers can encourage the plant to produce more blooms and prevent self-seeding. In late fall or early spring, cut back the stems to the base to encourage new growth.
How to Grow
STEP 1
Obtain blue vervain seeds from a reputable supplier or mature plants.
STEP 2
Prepare well-drained soil with a pH of 6.5 to 7.5.
STEP 3
Sow seeds in seed trays indoors 6-8 weeks before last frost.
STEP 4
Transplant seedlings to a sunny or partially shaded location with well-drained soil.
STEP 5
Water regularly and fertilize with organic fertilizer every two weeks during the growing season.
STEP 6
Deadhead spent flowers and cut back stems in the fall.
STEP 7
Harvest leaves and flowers in summer, dry and store for use in teas or tinctures.
How to Harvest
To harvest blue vervain, wear gloves to protect your hands and use sharp scissors or pruning shears to cut the leaves and flowers when the plant is in full bloom. Leave some stems on the plant for regrowth and to encourage pollinators. Avoid harvesting during wet conditions, as moisture can cause mold to grow on the harvested parts.
Dry the harvested parts in a warm, dry place out of direct sunlight until they are brittle. Once dry, remove the leaves and flowers from the stems and store them in airtight containers away from moisture and light. It’s important to discard any brown or moldy plant material before use, as this can affect the quality of the tea or tincture.With proper harvesting, drying, and storage techniques, you can enjoy the benefits of blue vervain all year round.
