Ah, calendula (aka marigold)! It is known to be a soothing remedy for skin.
According to Sade Musa at https://learningherbs.com/remedies-recipes/calendula-oil/ :
This powerful medicinal plant is beloved around the world, finding its way into countless home remedies and commercial skin care products, especially on account of its skin-restorative abilities. Calendula is a premier skin support herb with broad medicinal use. Applied externally, Calendula is a powerful wound healer: soothing traumatized, inflamed tissue and stimulating rapid growth of healthy skin cells.1 Calendula not only helps wounds heal quicker, it reduces their risk of becoming infected and scarred.2 The astringent, anti-inflammatory, and antioxidant properties of the herb grant its ability to not only treat, but prevent, sunburns3 – while its moistening nature hydrates dry, itchy skin. Calendula also has an affinity for the lymphatic system: addressing fluid stagnation, supporting the elimination of toxins, and relieving conditions such as varicose veins, bruises, and sore muscles. Massaging Calendula oil into your skin daily can help to achieve healthy, toned skin.

Please go to either of the above-listed websites to learn more about this calming, beneficial herb and how to prepare it for home use.
You can infuse calendula into a carrier oil, and then use that infused oil on your skin as-is, or as an ingredient in salves and ointments.
Please be sure to use organic calendula flowers and organic oil, so you’re not mixing unwanted chemicals in with your precious oil.
If you infuse calendula in oil, make sure to dry the flowers first, as the moisture in the flowers may cause the infusion to go rancid.
You may put the dried flowers into a blender first, to grind them slightly. This provides more surface area for the oil to absorb the good properties.
The basic recipe is to fill a glass container about ½ full with the dried flowers. Then fill the container almost full with your preferred carrier oil: I use jojoba most of the time, but other possibilities are olive oil, almond oil, avocado oil, or coconut oil.
Many recipes I see call for soaking the dried flowers in the oil in a warm spot (i.e., sunny window) for 4-6 weeks. Make sure the oil completely covers the flowers by a good margin to prevent air reaching the flowers and causing mold. Put a lid on it. Cover with a paper bag to protect from damaging UV rays. Shake the container once a day.
A faster method (anywhere from 4 to 24 hours):
- Use a heat-proof glass container, such as a Pyrex measuring cup or Mason jar. Do not put a lid on it.
- Use a low heat source such as a crock pot, yogurt maker, or oven; temp should be 250 – 300 degrees. Alternatively, you can use a warm-water bath: Create a double-boiler by placing a canning ring in the pan. Put the flower/oil container in the pan, and fill the pan with warm water (careful not to spill any water into the oil). Put the pan on the stove and turn the heat to lowest setting. Turn the burner off and on occasionally to maintain a temperature between 250 and 300 degrees.
- Continue heating for 4 – 6 hours, or until the oil takes on the deep color of the flower. If your temperature is low, it may take up to 24 hours.
- When the oil is ready, take it off the heat and allow to cool.
- Strain the oil through a potato ricer or fine mesh sieve.
- For more filtering, strain through a coffee filter.
- The calendula flowers can be composted.
- Store in a tightly covered glass container. Dark glass is preferred.
- If you store the oil in a cool, dark place, it should last 1 – 2 years. Or, keep the oil refrigerated until ready to use. When you use it as an ingredient in an ointment or salve or cream, etc., use that product within a few months.
