Chemical Composition and Nutritional Profile

Tansy contains a variety of bioactive compounds, including alkaloids, flavonoids, essential oils, and terpenes, which contribute to its medicinal properties.

The plant is particularly noted for its high concentration of thujone, a volatile monoterpene found in its essential oils, along with other compounds like camphor and paradichlorobenzene. Nutritional-wise, Tansy is low in macronutrients but contains trace amounts of vitamins such as vitamin C and some B-complex vitamins, along with minerals like potassium and magnesium. Its antioxidants, including flavonoids and phenolic compounds, help neutralize free radicals and reduce oxidative stress in the body.

The mechanism of action of Tansy involves stimulating the central nervous system through its volatile oils, which can have antispasmodic, analgesic, and antimicrobial effects when used in appropriate therapeutic contexts.

Forms, Preparation and Usage

Tanacetum vulgare has been traditionally used for its medicinal properties, with various forms available including fresh leaves, dried herb, tincture, powder, essential oil, and capsules.

It can be prepared as a tea by steeping dried leaves in hot water, or as a decoction by boiling the herb for a longer period.

Safety, Side Effects and Contraindications

Tanacetum vulgare can be used as a medicinal plant for its potential anti-inflammatory, antispasmodic, and analgesic properties, often employed in herbal remedies for digestive issues and respiratory conditions.

However, it may cause side effects such as nausea, vomiting, dizziness, and allergic reactions, particularly in individuals sensitive to chamomile or related plants. It should be used with caution as it may interact with certain medications, including anticoagulants and sedatives, potentially enhancing their effects or causing adverse reactions. Pregnant and breastfeeding women should avoid its use due to potential risks to the fetus or infant, and it is contraindicated in individuals with known allergies or gastrointestinal disorders.

For safe use, it is recommended to consult a healthcare professional before use, start with low doses, and discontinue use if any adverse effects occur.

Growing, Harvesting and Storage

Tanacetum vulgare grows best in well-drained, loamy soil with a slightly acidic to neutral pH, in full sun to partial shade, and requires regular watering during dry periods without becoming waterlogged.

It thrives in temperate climates and is relatively low maintenance, benefiting from occasional fertilization and weed control to promote healthy growth. The best time to harvest Tanacetum vulgare is during the flowering stage, typically in late summer, when the essential oils are most concentrated; the flowers and leaves should be cut with sharp shears to avoid damaging the plant. After harvesting, the plant material should be dried in a cool, dark, and well-ventilated area to preserve its potency, and once dried, it should be stored in airtight containers away from light and moisture.

Proper storage ensures the plant retains its medicinal properties for extended use in teas, tinctures, and other herbal preparations.
