*Sorry, but herbal medicine is
not useless - many modern rx cures are plant derivatives; they are simply hyped-up versions....although it is true that homemade herbals are usually less strong - which also makes them less dangerous. Aspirin was originally produced from willow bark. Willow bark was used for many hundreds of years for its fever-reducing and inflammation reducing properties, before anyone 'scientifically' discovered it and made pills out of it. Moldy bread was the basis for penicillin....two of the most crucial medicines we have today. Useless? Very funny. Modern rx tends to ignore any med that it cannot patent; and has a strong, obvious interest in discouraging and ridiculing natural medicine.
