York Cares for Clark

Clark wrote in his June 3 entry, “I have a bad Cold with a Sore throat.” He notes a few days later that York swam the Missouri River to a sand bar to collect “…a Sufficient quantity wild Creases [Cresses] or Tung [Tongue] grass.”
Cress (Lepidium sativum) was an herbal remedy administered in cases of asthma and on-going coughs. Tongue grass was likely the common chickweed, which was thought to have helped with pulmonary ailments. Both could have aided Clark’s cold and sore throat.
