 Ladies from a local Red Hat society are perched on stools around a bar in a greenhouse, clinking ceramic teacups. They've just had a workshop on herbal tea at Aaron's Meadow Herb Farm in the rolling fields of Clinton. The class was taught by farm owner Kathy Burke-Mahalzo, whose customers are mostly from Knoxville. She says interest in herbal remedies reflects the broader trend of wanting to know where our food and medicine come from. That went into overdrive during the coronavirus pandemic.
