DFU is a common and serious problem for diabetics. Treating it is difficult, particularly for people with weak immune systems.
Scientists have investigated the carotenoid content of Meliloti herba, a medicinal plant with anti-inflammatory effects. Using high performance liquid chromatography (HPLC) and column liquid chromatography (CLC), they isolated and identified the main carotenoid as (all-)-lutein 5,6-epoxide and tested its effects on primary sensory neurons and macrophages involved in inflammation. Results showed that lutein 5,6-epoxide reduced the activation of primary sensory neurons and decreased the release of IL-1β from macrophages. This suggests that lutein 5,6-epoxide could be used as an analgesic and anti-inflammatory treatment.
