That's pretty mess up. Preying on the Hmong elderly that can't read or understand English.
Some of those Hmong "doctors" that always advertise on the Hmong radio like to rip off the elderly too. My grandma bought a Roundys brand (Rainbow brand) honey for $10 at the flee market from these people who claim their medicine is the best. They told her that only the honey they sell is effective with their medicine, but you can buy it from Rainbow foods for like $2. It's funny that they claim it's their honey when the brand is clearly labeled on the container.
