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

Safety, Side Effects and Contraindications

Amaranthus spinosus can be used as a medicinal plant with potential therapeutic benefits, but it should be approached with caution due to its possible side effects and interactions.

While some studies suggest it may help with inflammation and oxidative stress, it can also cause gastrointestinal upset, allergic reactions, and, in high doses, may lead to toxicity. It may interact with medications such as anticoagulants, antidiabetic drugs, and immunosuppressants, potentially altering their effectiveness or increasing side effects. Special populations, including pregnant and breastfeeding women, should avoid amaranthus spinosus due to insufficient safety data, and individuals with chronic illnesses should consult a healthcare provider before use.

To ensure safe use, it is recommended to start with low doses, monitor for adverse reactions, and seek professional guidance when combining it with other treatments.

Growing, Harvesting and Storage

Amaranthus spinosus grows best in well-drained soil with a pH between 6.0 and 7.5, in full sun to partial shade, and requires regular watering to maintain consistent moisture without becoming waterlogged.

For optimal growth, it benefits from regular weeding and occasional fertilization with a balanced organic fertilizer during the growing season. Harvesting should occur when the plant has reached full maturity, typically 60 to 90 days after planting, by cutting the entire plant at the base using clean, sharp tools to ensure maximum yield and quality. To preserve its potency, the harvested plant should be thoroughly dried in a cool, shaded area or in a dehydrator, then stored in airtight containers in a cool, dark place or refrigerated to maintain its medicinal properties.

Proper storage prevents moisture loss and maintains the active compounds that contribute to its therapeutic value.
