It's most likely the Sensoril found in the Slimmer. It's a patented form of Ashwagandha.

Ashwagandha is most well-known and most often used for its sedative properties, as it has very strong relaxing and anti-anxiety effects. Even Ashwagandha's botanical name, Withania somniferum, echoes these effects as somniferum means, "sleep creator" in Latin. These sedative qualities make the herb very useful for those who need or want to break an addiction. We use it in the Slimmer to assist with emotional eating.
