What are the medicinal properties of Salvia lavandula?

Salvia lavandula helps with anxiety, insomnia, and restlessness due to its calming effects. The plant's essential oils, particularly linalool and linalyl acetate, contribute to its sedative properties. It's also used to relieve digestive issues, such as nausea and indigestion.

The active constituents of Salvia lavandula include flavonoids, terpenes, and phenolic acids.

Linalool, in particular, has been shown to inhibit the growth of certain bacteria and fungi.

The parts of the plant most used for medicinal purposes are its leaves and flowers. The leaves are rich in essential oils and are often used to make teas, infusions, and tinctures. The flowers, with their distinctive purple color, are used to make essential oils and are often used in aromatherapy.

Improper use of Salvia lavandula can cause drowsiness, headaches, and stomach upset. High doses of the plant's essential oils can also cause allergic reactions, including skin irritation and respiratory problems. It's essential to consult with a healthcare professional before using the plant medicinally.

When using Salvia lavandula medicinally, it's essential to follow proper precautions. Pregnant or breastfeeding women should avoid using the plant, as it can cause uterine contractions and affect milk production. Additionally, individuals with allergies or sensitivities to lavender or other members of the mint family should exercise caution when using the plant.

What are the horticulural aspects of Salvia lavandula?

Salvia lavandula grow best in well-drained soil with a pH between 6.0 and 7.0. Full sun to partial shade is required, with at least 6 hours of direct sunlight daily. Temperature range is 60°F to 90°F (15°C to 32°C), with some tolerance for heat.

Lavender sage prefers to be planted in the spring or fall, when temperatures are cooler. Space plants 12 to 18 inches apart, and 3 to 4 feet apart for a hedge. Water regularly, but avoid overwatering, which can lead to root rot. Fertilize lightly, as lavender sage is adapted to poor soil.

Harvest lavender sage flowers in the morning, after the dew has dried. Cut stems just above a leaf node, using sharp, clean scissors. Remove spent blooms regularly to encourage new flower growth. Harvest leaves at any time, but avoid over-harvesting, which can weaken the plant.

Pests common to lavender sage include aphids, whiteflies, and spider mites. Diseases include root rot, leaf spot, and powdery mildew. Regularly inspect plants for signs of infestation or infection, and treat promptly to prevent the spread of disease.
