Safety, Side Effects and Contraindications

Uncaria tomentosa, also known as cat's claw, can be used as a medicinal plant with potential therapeutic benefits, but it is important to be aware of its safety profile.

While generally considered safe when used in recommended doses, it may cause side effects such as gastrointestinal discomfort, nausea, and diarrhea in some individuals.

Growing, Harvesting and Storage

Uncaria tomentosa grows best in warm, humid climates with well-draining, nutrient-rich soil that is slightly acidic to neutral.

It thrives in partial to full sun, requiring at least 6 hours of direct sunlight daily, and benefits from consistent moisture without waterlogging. Regular pruning and weed control are essential for maintaining plant health, while mulching helps retain soil moisture and suppress weeds. The plant is typically harvested during the dry season, with the stems and leaves collected when they are fully mature, usually between late spring and early autumn, using clean, sharp tools to avoid damaging the plant.

For optimal potency, the harvested material should be air-dried in a cool, shaded area, then stored in airtight containers away from light and moisture, or refrigerated to preserve its medicinal properties.
