What are the therapeutic properties this herb?

The main therapeutic properties of Salvia officinalis are primarily attributed to its antioxidant activity, which helps protect the plant from oxidative stress and damage, and this activity is largely due to the presence of flavonoids and phenolic acids.

Additionally, the antimicrobial properties of Salvia officinalis, which allow it to inhibit the growth of various microorganisms, can be attributed to the volatile oils, including thujone, borneol, and camphor. Furthermore, the plant exhibits anti-inflammatory properties, which have been linked to the reduction of inflammation and pain, and are thought to be mediated by the saponins and polyphenols present in Salvia officinalis. Its antispasmodic properties, which enable it to relax smooth muscle and prevent spasms, have been associated with the sesquiterpene lactones, including costunolide and dihydrocostuslactone.

The neuroprotective properties of Salvia officinalis, which allow it to protect neuronal cells from damage and promote their survival, are thought to be mediated by the terpenoids and flavonoids present in the plant.

What are the medicinal constituents this herb?

The most important healing constituents of Salvia officinalis are rosmarinic acid, ursolic acid, quercetin, salvianolic acid b, and carnosic acid.

These compounds have been shown to possess significant antioxidant, anti-inflammatory, and antimicrobial properties, contributing to the plant's medicinal value. Rosmarinic acid has been found to exhibit potent antioxidant activity by scavenging free radicals and reducing oxidative stress, while ursolic acid has demonstrated anti-inflammatory effects by inhibiting the production of pro-inflammatory enzymes. Quercetin, salvianolic acid b, and carnosic acid have also been reported to possess antioxidant and anti-inflammatory properties, with quercetin exhibiting potential anti-cancer and cardiovascular-protective effects.

The combination of these compounds in Salvia officinalis may be responsible for its traditional uses in treating digestive issues, respiratory problems, and skin conditions, as well as its potential anti-inflammatory and antimicrobial properties.

What are the main herbal preparations this herb?

The main herbal preparations of Salvia officinalis are derived from its leaves and are used for medicinal and culinary purposes.

Salvia officinalis tea is made by infusing the leaves in hot water, often used for its antimicrobial and anti-inflammatory properties. A tincture of Salvia officinalis is prepared by soaking the leaves in a solvent such as ethanol, used to extract its bioactive compounds. Infused oil is prepared by steeping the leaves in a carrier oil, such as olive oil, to create a topical application for skin issues.

Salvia infusion and infused oil are also used in salad dressings to add flavor and potential health benefits.

What are the possible side effects of using this herb improperly?

The possible side effects of using Salvia officinalis improperly include experiencing nausea and dizziness due to its ability to induce a dissociative state and disrupt normal physiological functions.

Long-term and excessive use may abuse the kidneys by increasing the risk of renal damage and impairment. Salvia officinalis also has a potential to cause gastrointestinal issues such as diarrhea, possibly due to its effect on the gut microbiome and intestinal motility. Furthermore, individuals with pre-existing hypertension should exercise caution when using Salvia officinalis as it may exacerbate hypertension by increasing blood pressure and heart rate.

This is likely due to the plant's stimulatory effects on the cardiovascular system and its ability to increase sympathetic nervous system activity.
