For internal use, the recommended dosage for adults is typically 1-2 cups of tea per day, while children should only use it under medical supervision if safe.

Usage should be conservative, with short durations and frequent monitoring to ensure safety and efficacy.

Safety, Side Effects and Contraindications

Galium odoratum can be used with caution due to its potential to cause adverse effects, though it is generally considered safe when used in recommended doses.

Common side effects may include gastrointestinal discomfort, such as nausea or vomiting, and skin irritation upon topical application. It may interact with certain medications, particularly those affecting the central nervous system or blood pressure, so it is important to consult a healthcare provider before combining it with other herbs or drugs. Special populations, including pregnant and breastfeeding women, should avoid its use due to insufficient safety data, and individuals with chronic illnesses should also exercise caution.

To ensure safe use, always follow recommended dosages, consult a qualified healthcare professional, and discontinue use if any adverse reactions occur.

Growing, Harvesting and Storage

Galium odoratum grows in moist, well-drained soil in partial to full shade, preferring a slightly acidic to neutral pH.

It thrives in cool, temperate climates and requires regular watering to maintain consistent moisture without becoming waterlogged. To ensure healthy growth, it should be planted in a location with good air circulation and mulched to retain soil moisture and suppress weeds. For optimal yield, harvest the plant in early summer when the leaves and stems are at their most aromatic and potent, using clean scissors to cut the top portion just above the base.

After harvesting, the plant material should be dried in a cool, dark, and well-ventilated area to preserve its medicinal properties, then stored in airtight containers in a cool, dry place to maintain potency over time.
