Arnica oil is made by infusing arnica flowers in a carrier oil, such as olive oil, sunflower oil, or coconut oil.
The beneficial properties of arnica are attributed to its naturally occurring compounds, including sesquiterpene lactones, helenalin, flavonoids, coumarins, and carotenoids.
These components are believed to contribute to arnica’s soothing and comfort-enhancing qualities.
When a carrier oil is infused with arnica flowers, it absorbs these compounds, taking on the beneficial properties of the plant.
This study explored the potential of arnica-based products and noted their promise in various topical applications. (Note: Always consult a healthcare provider before using herbal remedies regularly.)
Many people include arnica oil in their self-care routine to help soothe muscles after physical exertion or to support general skin wellness.
I discuss the benefits of arnica oil in more details below. For now, here’s how to make arnica oil.
Arnica Infused Oil Ingredients
- ½ cup Dried Arnica Flowers
- 1 cup Carrier Oil (see options below)
- Glass jar with a tight seal
- Cheesecloth or Fine Strainer
Dried arnica flowers are the key ingredient when making this infused oil. It’s important to use completely dried flowers to avoid moisture buildup, which could cause premature spoilage.
The carrier oil serves as the base for your infusion. There are several options, each with unique properties (see the detailed section below on choosing the best carrier oil for your skin type).
Use a clean glass jar with a tight seal for steeping the flowers in oil. The seal prevents contamination and ensures the infusion process runs smoothly. Avoid using plastic containers, as they may leach chemicals into the oil.
You will need a cheesecloth or fine strainer to strain the oil, separating the arnica flowers from the liquid after the infusion.
Best Carrier Oil to Use for Different Skin Types and Preferences
The choice of carrier oil can significantly impact the quality and benefits of your arnica-infused oil. Here are the best options based on skin types and preferences:
Jojoba Oil
Best for: All skin types, especially oily and acne-prone skin.
Properties: Jojoba oil is a lightweight, non-greasy oil that closely mimics the skin’s natural sebum. It is highly moisturizing, absorbs quickly, and balances oil production without clogging pores. Jojoba is an excellent option for oily or combination skin.
Drawbacks: Jojoba oil can be expensive, but its versatility and skin compatibility make it a worthwhile investment.
Sweet Almond Oil
Best for: Normal to dry skin.
Properties: Packed with vitamins E and A, sweet almond oil is nourishing and soothing for normal to dry skin. It is lightweight and absorbs well, providing hydration without leaving a heavy residue. It’s also beneficial for improving skin tone and texture.
Drawbacks: Almond oil is not suitable for individuals with nut allergies and may not be as fast-absorbing as some lighter oils like jojoba.
Fractionated Coconut Oil
Best for: Dry or aging skin.
Properties: Fractionated coconut oil remains liquid at room temperature, making it easier to work with than solid coconut oil. It is deeply moisturizing and has antimicrobial properties, making it great for dry or mature skin. It also has a longer shelf life so your homemade arnica oil will last longer if infu
Drawbacks: Coconut oil may feel too heavy or greasy for oily or combination skin and can clog pores for those prone to acne.
Grapeseed Oil
Best for: Oily or acne-prone skin.
Properties: Grapeseed oil is lightweight, fast-absorbing, and won’t clog pores, making it perfect for oily or blemish-prone skin. It is rich in linoleic acid, which can help reduce inflammation and prevent clogged pores, contributing to clearer skin.
Drawbacks: Grapeseed oil has a shorter shelf life than other carrier oils.
Avocado Oil
Best for: Extremely dry, mature, or damaged skin.
Properties: Avocado oil is rich in fatty acids and vitamins, which help restore skin elasticity and moisture. It’s an excellent choice for skin that needs extra nourishment, such as mature or sun-damaged skin.
Drawbacks: This oil is heavier and oilier, making it less suitable for those with oily or acne-prone skin. I used avocado oil in this recipe.
Olive Oil
Best for: Dry or sensitive skin.
Properties: Olive oil is rich in antioxidants, vitamins A and E, and moisturizing compounds, making it a great choice for dry, rough, or irritated skin. It helps soothe and nourish the skin while promoting skin elasticity.
Drawbacks: Olive oil can feel heavy and greasy, which may not be ideal for oily skin or those who prefer a lighter texture.
Choosing the right carrier oil for your arnica infusion allows you to tailor the end product to meet your specific skin care needs.
How To Make Arnica Oil: Step-by-Step Infusion Process
Here’s a detailed guide on how to make arnica-infused oil using the stovetop low-heat method, with the sun infusion method as an alternative option.
Step 1: Fill A Glass Jar with Dried Arnica Flowers and Carrier Oil
Place completely dried arnica flowers in a clean glass jar, filling it about half to two-thirds full.
Pour your chosen carrier oil over the flowers until they are completely submerged. The oil must cover the flowers completely, as any exposed plant material can cause spoilage.
Step 2: Heat The Oil On The Stovetop (Low-Heat Method)
Place the jar with the flowers and oil into a saucepan filled with a few inches of water (creating a double boiler effect). Use a double boiler if you have one.
Heat the water over low heat to gently warm the oil. Do not rush this process. You don’t want the oil to boil or become too hot, as this can degrade the beneficial properties of the oil and the arnica.
Keep the oil warm for 2-3 hours, checking the temperature to ensure it stays low and does not exceed 120°F (49°C). Stir the oil occasionally to encourage even extraction.
Once the oil has been infused with the arnica, remove the jar from the heat and let it cool completely before moving to the next step.
Step 2: Sun Infusion Method
If you prefer a slower, gentler method, seal the jar with a tight lid and place it in a warm, sunny spot, like a windowsill.
Leave the jar in the sun for 4-6 weeks, shaking it gently every few days to help the flowers release their beneficial compounds into the oil.
Be sure to monitor the oil during this period to ensure that it doesn’t become rancid.
Step 3: Strain the Infused Oil
Once the infusion process is complete, it’s time to strain the oil.
Use a cheesecloth or fine strainer to separate the arnica flowers from the oil. Pour the oil through the strainer into a clean bowl or container, squeezing out any remaining oil from the flowers.
Step 4: Transfer and Store the Oil
After straining, pour the infused oil into a clean, dry glass bottle or jar with a tight-fitting lid to protect it from exposure to air, which can cause the oil to go rancid over time.
Label the bottle with the date and contents for easy identification.
Store the infused oil in a cool, dark place such as a pantry or cupboard to preserve its quality. Properly stored, arnica-infused oil can last for up to a year.
I usually transfer a small amount of infused oil into a small pump bottle. This does two things – It limits exposure to air and light and makes it easy to apply without dipping your fingers into the oil.
Adjusting The Infusion Time
The longer you infuse the arnica, the more potent the oil will be. If you prefer a milder oil, you can shorten the infusion time.
The viscosity of the carrier oil can also affect infusion time. Thicker oils like coconut oil may require a longer infusion period.
Don’t be afraid to experiment with different infusion times to get the results you want.
Once you’ve achieved the desired infusion strength, add vitamin E oil to the strained oil. Vitamin E acts as a preservative.
3 Tips for a Successful Infusion
Tip 1. Shake the jar every few days to distribute the oil evenly over the flowers and encourage the release of their medicinal properties into the oil.
Tip 2. Use clean, sterilized equipment to avoid contamination and ensure the longevity and purity of the oil.
Tip 3. Check the oil periodically for signs of rancidity, such as a sour smell or cloudiness. Discard if rancid and make a fresh batch.

Precautions When Using Homemade Arnica Oil
Do Not Use on Broken Skin: Arnica oil is for external use only. Avoid using it on open wounds, broken skin, or areas with irritation, as it may cause a reaction.

Store the infused oil in a cool, dark pantry or cupboard away from direct sunlight, heat sources, and excessive humidity.
