#12. The difference between essential oils and extracts

Original article published on LinkedIn, also on his website, 23 June 2021, by: Nuqo Trading

“With the increased awareness of natural products, more people are asking questions about the difference between essential oils and extracts. Both play an important role in natural wellness products used in everything from aromatherapy to teas, and the right process is essential to get the most out of these natural substances.

The main difference between essential oils and extracts is the process. While both are extracted from different parts of the plant, the process is very different. Essential oils must be extracted through distillation, while extracts are steeped in a liquid to isolate the flavor.

Oils collected from the aromatic parts of flowers, roots, and leaves are known as essential oils. These oils are concentrated in nature and prepared by steam distillation. The plant parts are placed inside a steam chamber, steam is released over the plant parts, and the oils are collected by squeezing under steam pressure. The extracted substances are collected in the vapor chamber and cooled in a condenser. The condenser creates water and separates the oil into a concentrated form.

With extracts, the plants go through a steeping process, where the collected substance is concentrated. This can also be done by pulverizing the plant. The most common extraction process is herbal tea, while tinctures require the plant material to be steeped in alcohol for a long time to remove the essential compounds.

Each method removes the most important compounds from plants and concentrates the best of nature into a simple, easy-to-use substance.”

My question to Nuqo Trading:

In my handmade soap production1, I use olive oil, which has been infused with 720 grams of herbs such as rosemary, oregano, sage, lavender, in 15 liters of olive oil. The infusion time is half a year. Then the soaked herbs are filtered out, and powdered in the food processor, filtered again and returned to the added oil, so that everything that is possible to extract from the soaked herbs is retained and used in the soap production. The infused olive oil looks black when the grinding and back-filtration are done. The smell is extraordinary. Next to that, I use a tea from the same herbal extract (for many days), which is also very dark. I use this tea to create a lye with sodium hydroxide. Later, when the liquid starts to saponify, I add the necessary amount of essential oil of the same herb for that batch.

My question is: is the result of infusion, and the way I make the oil, also a kind of extract?

Answer on LinkedIn, by Nuqo Trading:

Most likely! Your soaps sound amazing!

In the video you can follow the creation of (in this case) lavender soap, from lavender fields to infusion, to cutting and packaging:

#7. Rosemary-infused body oil

The benefits of the herb rosemary, or rosmarinus officinalis 1 2 3, were already hailed in the Minoan Civilisation 4. Rosemary is a kitchen herb, but a medicinal herb as well. Medicinal herbs 5 6 7 8 are available as tinctures, tablets, pills, teas and essential oils. These are for internal use and oral use. Essential oils, however, are also used externally. The term medicinal is an indication that nobody should use these without consulting a well-trained professional therapist, or a medical doctor who also studied these herbs and/or their oils, how to use these, when, for which health problems, and what the dosage should be.

Rosemary is known for its benefits for the skin. It is present in almost all skin products, like shampoos, creams, massage oils, and body oils. Four out of seven Cretan Garden soaps are made out of rosemary-infused olive oil 9, oregano-infused oil 10 and sage-infused oil 11.

Your home-made body oil and body scrub

Body oils are expensive. You can make your own body oil. Your skin will love it, and your wallet as well. Follow the next steps and enjoy the result.

  1. 500 ml organic extra virgin olive oil
  2. 30 grams dried organic rosemary leaves
  3. Put the dried rosemary in a casserole that is big enough for the half-litre olive oil plus the 30 gram rosemary leaves. Warm the oil up to 38–60 degrees Celsius and keep the casserole at this temperature for about 48–72 hours. During this time, all the goods are extracted from the leaves into the oil. This process is called infusing. Another method: add the olive oil and herbs to a bowl, or casserole and keep it for some weeks in a warm sunlit spot in the house. Stir the oil-rosemary mix during the infusing time every day. I infuse olive oil as well, for making soap, but I offer the oil more time to infuse. At least three months. 
  4. When the oil is infused, you can filter the herbs out, by using a sieve. If you want to make rosemary pulp, you can add the oily herbs to the kitchen machine and pulverise them. 
  5. Take an empty bowl or casserole, and put a cheesecloth in the sieve. 
  6. Put the rosemary-olive-oil pulp from the kitchen machine cup into the cheesecloth, and let it leak out for a while, till all the oil has disappeared. 
  7. Make this process more efficient by pouring the filtered oil for the second time over the pulp. At the end, you can take the rest of the oil from the pulp when you take the four points of the cheesecloth together and press the oil out. Your hands will become very oily, but you can remove this with kitchenpaper.
  8. Fill an empty, well-cleaned and dried fluid soap dispenser and add about 20 drops of rosemary essential oil, or an essential oil of your own choice.
  9. The rest of the infused oil can be stored in a cold place, for instance in the refrigerator. Put a lid on it.
  10. The left-overs of the rosemary pulp in the sieve can be used as a body scrub. You can store it, for instance, in an empty, clean, glass jar in the refrigerator. Before using a body scrub to exfoliate your skin, read my blog post: Exfoliating the skin 12.

How to use the body oil

The best moment to use body oil is after a shower or bath, before drying your body with a towel. Pump some body oil from the dispenser into the palm of one of your hands and divide the oil over both hands. Apply the oil on the entire body. Massage the oil onto the warm and wet skin. In this way, you do not need so much oil, the oil is easier to spread, and because the skin is warm, the oil is easily absorbed. Then pat the skin dry. You will discover that the skin is not oily, and after drying the skin shines and looks younger and healthier. In case your skin is really dry, it will take some weeks before your skin is back to normal again. You can use body oil every day.

Instead, you could massage the entire body from head and hair to toes according to the Indian abhyanga massage before taking a shower. Read more about this massage in my blog post “The skin” 13. The used oil is also an herbal-infused body oil.

Other uses: after a day at the beach, in the sunlight, in the hot dry wind, the salty seawater, or in winter when being outside in the cold, or 24/7 in a warm dry room. You can use the rosemary body oil also as a hair mask.

Attention: the rosemary aroma is uplifting, stimulating, energising, and therefore best not to be used before sleeping. If you would like to create a body oil for a good night’s rest, use lavender instead of rosemary.
