The research on Lavandin (Lavandula x intermedia) shared here explores how effective Lavandin’s therapeutic properties might be. The first study considers its calming properties and explores whether using this oil will help to reduce preoperative anxiety in surgical patients. The second study investigates its potential antibacterial and antifungal activity, while the third compares its antioxidant potential against that of true Lavender (Lavandula angustifolia).

The Use of the Essential Oil Lavandin to Reduce Preoperative Anxiety in Surgical Patients

Preoperative anxiety is prevalent in surgical patients who may require anxiety medications, thus impacting preoperative teaching and patient satisfaction. No studies were found in a comprehensive search on the effect of essential oils on anxiety in the preoperative setting. The purpose of this experimental study was to investigate whether the essential oil lavandin is more effective than standard care in reducing preoperative anxiety. A convenience sample of 150 adult patients were randomly assigned to either control (standard care), experimental (standard care plus essential oil lavandin), or sham (standard care plus jojoba oil) groups. Visual analog scales were used to assess anxiety on admission and OR transfer. Controlling for baseline anxiety and pain, the lavandin group had significantly lower anxiety on OR transfer, suggesting that lavandin is a simple, low-risk, cost-effective intervention with the potential to improve preoperative outcomes and increase patient satisfaction. Future studies should test the effects of lavandin in the postoperative phase and in specific populations with documented high anxiety.

This study aimed to evaluate the in vitro antibacterial and antifungal activities of Lavandula intermedia Emeric ex Loisel. ‘Budrovka’, an indigenous Croatian cultivar of lavandin. For that purpose the activity of ethanolic extracts of flowers, inflorescence stalks and leaves against thirty one strains of bacteria, yeasts, dermatophytes and moulds were studied using both the agar well diffusion and broth dilution assays. Among the investigated extracts found to be effective against a broad spectrum of microorganisms, the flower extract was considered to be the most potent one. Linalool and rosmarinic acid, as the most abundant constituents found, are very likely major contributors to the observed antimicrobial effects. The results suggest that flowers of lavandin ‘Budrovka’ could serve as a rich source of natural terpene and polyphenol antimicrobial agents.

A Croatian indigenous cultivar of lavandin, Lavandula x intermedia ‘Budrovka’ (Lamiaceae) was studied for the phenolic acids, flavonoids, anthocyanins, procyanidins and total tannins, as well as total polyphenols content, in the flower, inflorescence stalk and leaf ethanolic extracts. Antioxidant potentials on these plant part extracts were assessed by the DPPH free radical scavenging activity, iron chelating activity, reducing power, lipid peroxidation inhibition properties and total antioxidant capacity assays. All results were compared with those of Lavandula angustifolia, the only member of the Lavandula genus officially used in modern phytotherapy. Based on the results of our parallel study, we may suggest that Lavandula x intermedia ‘Budrovka’ is as potent an antioxidant as Lavandula angustifolia and the antioxidant activity of the Lavandula extracts is mainly due to the presence of rosmarinic acid. A good correlation was found between the polyphenol contents and antioxidant activities of the extracts.
