The plant can be prepared as a tea by steeping dried leaves in hot water, or as a decoction by boiling them for a longer period, while an infusion involves soaking the leaves in cold water. Topical applications include using the powder or essential oil for skin conditions, and capsules are often used for internal consumption. For adults, a typical dosage is 1-2 grams of dried leaves in tea form, taken up to three times daily, while children should only use it under medical supervision, with a reduced dosage.

Due to its potent nature, it is recommended to use senna auriculata sparingly and for short durations, typically no longer than a week, to avoid adverse effects.

Safety, Side Effects and Contraindications

Senna auriculata can be used as a herbal remedy for its laxative and anti-inflammatory properties, but it must be used with caution due to its potential side effects.

While generally safe when used in moderate amounts and for short durations, it may cause gastrointestinal discomfort, including cramping, diarrhea, and electrolyte imbalances. Long-term or excessive use can lead to dependency, nutrient deficiencies, and intestinal damage, making it unsuitable for chronic use. It may interact with medications such as diuretics, anticoagulants, and laxatives, potentially enhancing their effects or causing adverse reactions. Special populations, including pregnant and breastfeeding women, should avoid senna auriculata due to risks of miscarriage or infant toxicity, while individuals with chronic illnesses like irritable bowel syndrome or diabetes should consult a healthcare provider before use.

To ensure safety, it is advisable to use senna auriculata under professional guidance, follow recommended dosages, and discontinue use if adverse effects occur.

Growing, Harvesting and Storage

Senna auriculata grows best in well-drained, loamy soil that is rich in organic matter, with a pH range of 6.0 to 7.5.

It thrives in full sun to partial shade and requires regular watering during the growing season, though it is relatively drought-tolerant once established. To ensure optimal growth, it should be planted in a location with good air circulation to prevent fungal diseases, and regular weeding and mulching can help retain moisture and suppress weeds. Harvesting is best done during the flowering season, typically in late summer to early autumn, when the leaves and pods are mature but still tender; the leaves should be carefully plucked by hand or with pruning shears to avoid damaging the plant.

After harvesting, the plant material should be dried in a shaded, well-ventilated area to preserve its potency, then stored in airtight containers away from light and moisture to maintain its medicinal properties for extended periods.
