Goldenrod Total Hydrosol - Two Ounce Sprayer
Early Goldenrod Solidago juncea can be distilled in July when it is in full bloom. So far, our results have come from a total distillation of the aerial parts of the flowering herb. It is a native of North America and a member of the diverse Asteraceae family. There are over a hundred species of goldenrod. Many, are native to the Americas. In aromatherapy, those that have been distilled have demonstrated healing uses. Some are known for inflammation and skin health. Historically, various species of Goldenrod were used to heal wounds in China and in the Americas, presumably before these people groups had contact. It was also used historically to make natural dyes for wool. The name for the taxon, Solidago, is derived from a Latin word for whole, as in, made whole, or healed. English writings reference this herb in some of their old folk remedies. Dozens of uses are listed for the various European varieties, especially in healing teas. Furthermore, new compounds are still being catalogued for this species. There is opportunity for a great deal more research regarding the natural compounds in this botanical grouping. The CRC World Dictionary of Medical and Poisonous Plants lists S. juncea as “stomachic” meaning it aids in appetite and digestion. The roots specifically are listed as anti-convulsive and febrifuge. The total plant is listed as a possible treatment for jaundice. Treatments from the leaves are listed to aid with treatment of diarrhea. Again, there are various treatments derived for antiemetic uses and fevers. For other folk medical remedies see Iroquois Medical Botany by James Herrick. These remedies are all based on parts of the fresh herb and not steam distilled oils. It is a common fallacy to attribute the same healing properties to the volatile content alone. Don’t do this.
Aromatherapy literature is rare and ambiguous specific to the various Goldenrod types, but the following uses have also been mentioned in aroma therapy: Varicose veins, skin issues, high blood pressure and others.
Commercially there is great promise with this herb. The entire herb, root to tops, can be distilled. The yield is decent and the majority of the oil comes over fairly early in the process. EOQA has experimented with total distillation and confirmed yields of over one percent. The extra preparation of controlled drying, mulching and managing heat and pressure, could produce significantly higher yields and more attractive floral waters and oils. EOQA has not confirmed root yields. The recovered oils are being tested now and we will publish our findings soon.
The hydrosol produced from this herb has a strong earthy, herbal note with a persistent vegetable-aroma, somewhere between celery and sweet corn. If the hydrosol is any indication there could be flavor applications, especially in savory dishes. There is one negative detail on that front however; there are faint sulfur notes in the fresh hydrosol. The distilled oil has a strong terpene character but until the results are back I see no reason to speculate.The roots were evaluated, and while very dry, they possess a strong earthy-herbal-medicinal scent. EOQA intends to conduct part-specific research
