Shankhpushpi (Convolvulus pluricaulis) is a plant that is traditionally used in Ayurvedic medicine to improve memory and cognitive function. Some people also use it as a natural remedy to lower blood pressure, boost immunity, and improve digestion. However, there is limited scientific evidence to support these uses of shankhpushpi. It is important to note that herbs can interact with other medications and may not be safe for everyone, so it is always best to consult a healthcare professional before using any new supplement or herbal remedy.
