Cited from Bliss and Blessings: the Divine Alchemy of the Star Flower and Gemstone Essences by Star Riparetti:
"The most traditional way to take essences is orally, dropping the drops on or under the tongue from the dropper. There is faster absorption under the tongue, as there is a major meridian under the tongue that disperses the essence out to the entire meridian and chakra system... You can also put the drops in water and sip it. My first guideline for using essences: Take as directed (by your own divine director). Avoid touching the dropper to your tongue (or anything else). We don't want to grow things- like bacteria- in the bottle.
Essences work very nice topically, as well. They are absorbed through the skin by osmosis... Apply essences topically to any part of the body that is calling for comfort and support... Rub or drop drops on pulse points, the temples, wrists, behind ears... on forehead, back of neck, the bottom of feet... Put the essence on a cotton swab and pulse it in a stimulating rhythm, and sometimes go in a circular pattern... Rub in the palms of your hands and fan them through the aura.
Essences are very good in baths. Bathing with them (and essential oils- I like both) is awesome... You can mix essences in with the oils you are using for massage. (This is very powerful, and great for the massage therapist as well as the recipient, as the hands are absorbing.) Mix them with essential oils any time to add to their vibrational energies. You can put them into oils, potions, lotions and creams... The essences are great in misters and spray bottles. [We offer essence and essential oil blends in our Sprays and Mouth Mists, as well as Topical Oil Blends.]
Chiropractors have reported that adjustments hold better when the person is using essences. Acupuncturists are getting good results by using the drops on meridians and pressure points, often on q-tips, instead of needles. Essences have been described as liquid acupuncture. They move energy."
