Conventional Medicinal Uses

Salvia sclarea, commonly known as Clary Sage, has been the focus of various scientific studies due to its diverse medicinal applications in conventional medicine.

Key studies have highlighted its potential in treating different health conditions, based on its active components, particularly sclareol, a diterpene alcohol.

• Dysmenorrhea (Painful Menstruation): A 2022 study[1] investigated the effectiveness of Salvia sclarea essential oil in treating dysmenorrhea. The study focused on the pain-relieving effects of sclareol, a component of the essential oil.
  It was found that sclareol inhibited various inducers of uterine contraction and possessed analgesic effects in animal models. These findings suggest sclareol as a potential alternative supplement for dysmenorrhea.
• Anti-inflammatory Effects: Salvia sclarea’s anti-inflammatory properties have been explored, particularly in the context of labdane diterpenes, a family of compounds to which sclareol belongs.
  Sclareol was found[2] to significantly reduce inflammatory severity in animal models of atopic dermatitis and rheumatoid arthritis. It achieved this by inhibiting NF-κB translocation and phosphorylation of MAPK signaling, which are key pathways in inflammation.
  These findings underline its potential in treating inflammatory conditions.
• Anti-hypertensive and Anti-diabetic Effects: Research[3] has also shown that sclareol can reduce blood pressure in rats, suggesting its potential as a hypotensive agent in cardiovascular diseases.
  Furthermore, sclareol has been implicated[4] in the improvement of hyperglycemia-induced renal injury, which is significant in preventing diabetic nephropathy.
  This indicates its potential application in the treatment of hypertension and diabetes.
• Spasmolytic and Bronchodilator Actions: A study[5] evaluated the traditional use of Salvia sclarea as a spasmolytic and bronchodilator agent. The study found that methanolic extracts from Salvia sclarea exhibited significant spasmolytic effects on gastrointestinal and respiratory spasms.
  These findings suggest potential applications of Salvia sclarea in complementary medicine for treating gastrointestinal and respiratory diseases.
• sedative and stress reducing effects: Research indicates that Salvia sclarea (Clary Sage) does have sedative effects.
  In a randomized controlled trial, the inhalation of Salvia sclarea essential oil vapors was shown to significantly reduce systolic blood pressure, diastolic blood pressure, and respiratory rate in female patients with urinary incontinence undergoing urodynamic assessments[6].
  These results suggest the oil’s potential in inducing relaxation and reducing stress.
  Another study[7] assessed the antidepressant effects of Salvia sclarea essential oils in rats, revealing that clary oil had a significant anti-stressor effect.
  This effect was associated with the modulation of the dopamine pathway, indicating the oil’s potential as a therapeutic agent for depression.
  Additionally, a study[8] assessing the effects of Salvia sclarea on chronic immobilization stress-induced endothelial dysfunction in rats found that treatment with clary sage significantly reduced systolic blood pressure and heart rate.
  The study concluded that clary sage might be effective in preventing and treating stress-induced cardiovascular diseases.ns.

Recommended Dosages

• Determining the recommended dosage of Salvia sclarea, particularly for children, is challenging due to the lack of specific scientific studies addressing this.
  Most existing research focuses on adult usage, and even then, quantifying the right dose for aromatherapy or other uses is difficult due to the varied bioactive compounds in Salvia sclarea.
• For aromatherapy, the general guideline is to use enough to confer a pleasant aroma, such as lighting incense sticks.
  However, this is quite subjective and varies based on individual preference and sensitivity. In some studies[9], a cream containing a mix of Clary Sage and other essential oils was applied on the abdomen, but again, these concentrations were specific to the study design and not standardized dosages.
• For children, the situation is even more complex. Children’s bodies react differently to herbal treatments, and what is safe for an adult may not be safe for a child. Without specific studies or clinical trials on children, it’s not possible to recommend a safe and effective dose of Salvia sclarea for them.

Extensive studies have shown that clary sage oil enhances the brain’s production of dopamine and 5-HT, both key neurotransmitters associated with positive mood and well-being.
