Today, calendula is prized as a homeopathic remedy, but the essential oil extracted from the petals (called calendula oil) is just as valuable for promoting your health. To maximize its potency and shelf life, proper storage is essential. In this article, we’ll look at how to properly store calendula oil to ensure its longevity.
What is Calendula Oil?
Calendula oil is simply oil infused with dried calendula flowers. Soak the flowers in a carrier oil like olive or jojoba oil for several weeks or longer. You can use the entire dried flower head or just the petals, but it’s important to make sure they are completely dry. When steeped, the natural active resins within the calendula are extracted and absorbed into the oil.
Finished calendula oil can be used alone or as an ingredient in other natural salves, ointments, or creams! Your options for using calendula oil depend somewhat on the carrier oil you choose to use to create your infusion. For example, some oils are not edible, while others may not be so good for your skin.
Making your own calendula oil is easy and much cheaper than most other natural, high-quality skin care products on the market.
Essential Tips for Storing Calendula Oil Safely
- Utilizing Dark and Airtight Containers
When it comes to storing calendula oil, the choice of containers plays a significant role. It is essential to use dark, glass containers that are specifically designed to block out light. Exposure to sunlight can degrade the oil’s quality and reduce its shelf life. Dark containers, such as amber or cobalt blue glass bottles, protect the oil from harmful ultraviolet (UV) rays, preserving its potency and extending its shelf life. Additionally, airtight containers help minimize oxidation by preventing air from entering and disrupting the oil’s chemical composition.
- Storing in Cool Temperatures
Calendula oil is sensitive to heat, which can accelerate its deterioration and spoilage. To ensure a longer shelf life, it is crucial to store calendula oil in a cool environment. Ideally, temperatures between 40°F (4°C) and 60°F (15°C) are optimal for preserving the oil’s freshness and nutrient content. Avoid storing it in areas prone to temperature fluctuations, such as near stoves or windows, as these can expose the oil to excessive heat and compromise its quality.
- Shielding from Sunlight and Moisture
In addition to utilizing dark containers, protecting calendula oil from sunlight and moisture is essential. Direct exposure to sunlight can cause the oil to oxidize and degrade, leading to a shorter shelf life. It is advisable to store the oil in a cool, dark cabinet or pantry away from windows or other sources of natural light. Moisture can also adversely affect the oil’s quality, potentially leading to mold growth or rancidity. Therefore, it is important to ensure that the storage area is dry and free from humidity.
- Periodically Checking for Rancidity
To maintain the potency and freshness of calendula oil, it is crucial to periodically check for signs of rancidity. Over time, oils can become rancid due to exposure to air, heat, or moisture. Rancid oil has an unpleasant odor and may exhibit a yellow or brown coloration. It is advisable to inspect the oil regularly, especially if stored for an extended period. If any signs of rancidity are detected, the oil should be discarded and replaced to ensure optimal quality and efficacy.
- Properly Sealing and Labeling Containers
To prevent air, light, and moisture from affecting calendula oil, ensuring proper sealing of containers is vital. Tighten the lids securely to create an airtight seal, minimizing the oil’s exposure to oxygen. It is also recommended to label the containers with the date of purchase or extraction to keep track of the oil’s age. This helps avoid using expired oil and enables you to prioritize using the oldest oil first to prevent waste.
