A woman has been blinded after a herbal shop sold her betel nut juice to use as EYE DROPS to treat her cataracts. Kamnang Suwanna, 56, visited the alternative medicine store to find a remedy for her aching joints two months ago in Khon Kaen, Thailand. She bought the solution - made from areca nut - but the assistant noticed her cataracts and also recommended that she buy another bottle for putting the liquid in her eye. Kamnang declined - but after drinking the betel nut juice for a month and noticing an improvement in her mobility she decided to return to the 'King's Herbs'' shop and buy more to try in her eyes.
