The recommended dosage for adults is typically 1-2 grams of dried root per cup of tea, while children should only use it under medical supervision if deemed safe.

Due to its potent nature, it is advised to use armoracia rusticana sparingly, with a frequency of no more than 2-3 times per week and a duration not exceeding a few weeks, to avoid potential adverse effects.

Safety, Side Effects and Contraindications

Armoracia rusticana can be used as a medicinal plant for its potential digestive and anti-inflammatory properties, but it should be approached with caution due to its potential side effects and interactions.

Common side effects may include gastrointestinal discomfort, such as nausea, vomiting, and diarrhea, as well as allergic reactions in sensitive individuals. It may interact with medications such as anticoagulants, antiplatelet drugs, and certain antidiabetic agents, increasing the risk of adverse effects. Pregnant and breastfeeding women should avoid its use due to insufficient safety data, and it is contraindicated in individuals with chronic digestive disorders or those undergoing surgery.

For safe use, it is recommended to consult a healthcare provider, start with low doses, and monitor for any adverse reactions.

Growing, Harvesting and Storage

Armoracia rusticana grows best in well-drained, loamy soil with a slightly acidic to neutral pH, thriving in full sun to partial shade and requiring consistent moisture without becoming waterlogged.

It prefers cool climates and is typically planted in early spring after the last frost, with seeds or transplants spaced about 12 to 18 inches apart to allow for adequate growth. Regular watering and mulching help maintain soil moisture, while periodic weeding and hilling up the soil around the base can promote root development and protect against pests. Harvesting should occur in late summer to early fall when the leaves are fully mature and the roots are most potent, using a spade to carefully dig up the entire plant to avoid damaging the root system.

After harvesting, the roots should be thoroughly washed, sliced, and dried in a cool, dark place with good air circulation, then stored in airtight containers in a cool, dry location to preserve their medicinal potency and extend their shelf life.
