It usually occurs within 6 to 8 hours after consumption, though some individuals may react within 3 to 4 hours, while others might not experience effects until around 10 hours later.

Generally, the time it takes to experience diarrhea after drinking senna leaf tea varies from person to person. It usually occurs within 6 to 8 hours after consumption, though some individuals may react as early as 3 to 4 hours, while others might not experience effects until around 10 hours later. A detailed analysis is as follows:
The onset time of senna leaf's effects is influenced by factors such as dosage, individual constitution, and fluid intake. A higher dose tends to produce a stronger stimulation of the intestines, leading to a faster effect. Individuals with sensitive gastrointestinal systems may also respond more quickly. Consuming the herb with sufficient warm water helps dissolve and absorb its active components, promoting intestinal motility and shortening the onset time. It should be noted that senna leaf is a stimulant laxative and may cause discomfort such as abdominal pain and bloating during diarrhea. Long-term use is not recommended, as it may lead to intestinal dysfunction and worsen constipation.
Dosage should be strictly controlled to avoid excessive intake that could cause severe diarrhea. For daily bowel management, it is better to improve defecation through dietary adjustments and increased physical activity, thereby reducing reliance on medication.
