Natreon of the United States has obtained a patent for “an extract obtained from the Ashwagandha plant taken from steep rocks in the Himalayan mountains,” officials of the patent facilitating cell said in their report. The report said another US establishment, the New England Deaconess Hospital, has taken a patent on an Ashwagandha formulation claimed to “alleviate symptoms associated with arthritis.” “One thing which is very obvious from the above study,” the report concluded, “is that Ashwagandha plant is catching attention of scientists and more and more patents related to Ashwagandha are being filed or granted by different patent offices of the world since 1996.” (PTI)
