NEW DELHI: Price of psyllium husk—popular as ‘isabgol’ in India—is rising in the spot and future markets because of low production, and traders said the rates in the weeks ahead would depend on purchases by big companies including ITC, Dabur, Perrigo Company and Proctor & Gamble. According to traders, buyers are waiting for farmers and stockists to offload stock, which would reduce its price. They said companies are purchasing less because of the high price.
