The preparation methods vary, with common approaches such as making a tea by steeping dried leaves in hot water, decocting the plant material for stronger extracts, or creating an infusion for mild effects. For topical use, the plant can be crushed and applied directly to the skin or mixed with a carrier oil for poultices or salves. The recommended dosage for adults is typically 1-2 grams of dried leaves in a tea or 1-2 capsules per day, while children should only use it under medical supervision, with a lower dose if deemed safe.

It is advised to use ageratum conyzoides sparingly, with a maximum duration of 1-2 weeks unless otherwise directed by a healthcare professional.

Safety, Side Effects and Contraindications

Ageratum conyzoides can be used as a medicinal plant with potential benefits, but it also carries certain safety concerns.

While some studies suggest it may have anti-inflammatory, antimicrobial, and antidiabetic properties, its use is not without risks. Potential side effects include gastrointestinal upset, allergic reactions, and skin irritation, especially with high doses or prolonged use. It may interact with certain medications, such as anticoagulants or diabetes treatments, so caution is advised when combining it with other drugs or herbs. Special populations, including pregnant and breastfeeding women, should avoid ageratum conyzoides due to insufficient safety data, and individuals with chronic illnesses should consult a healthcare provider before use.

For safe use, it is recommended to follow recommended dosages, consult a qualified healthcare professional, and monitor for adverse reactions.

Growing, Harvesting and Storage

Ageratum conyzoides grows best in well-drained, loamy soil with a slightly acidic to neutral pH, requiring full sun to partial shade for optimal growth.

It thrives in warm climates with moderate rainfall, needing regular watering to keep the soil consistently moist but not waterlogged. Regular weeding and pruning are essential to promote healthy growth, while fertilizing with a balanced NPK fertilizer every few months ensures robust development. The plant is typically harvested when the leaves are fully developed and the stems are mature, usually around 4 to 6 months after planting, by cutting the stems just above a node to encourage regrowth.

For storage, the harvested material should be dried in a shaded, well-ventilated area to retain potency, then stored in airtight containers away from light and moisture to preserve its medicinal properties.
