Castor oil, derived from the seeds of Ricinus communis, has a long history of use in traditional medicine, particularly for addressing issues related to swollen lymph glands and supporting lymphatic drainage. Traditionally, castor oil packs—cloths soaked in castor oil and placed on the skin—are applied over areas of lymphatic congestion or swelling. This practice is most notably rooted in folk and naturopathic traditions, with proponents like Edgar Cayce popularizing castor oil packs for a variety of ailments, including lymphatic and glandular issues, in the early 20th century.

However, scientific evidence supporting the efficacy of castor oil for treating or reducing swollen lymph glands is limited. A few small studies suggest that topical application of castor oil may increase lymphocyte count and enhance certain immune parameters, but these studies are often of low quality, involve small sample sizes, or are not directly focused on lymphadenopathy (swollen lymph nodes). There is little to no robust clinical evidence to confirm that castor oil packs have a significant or reliable effect on swollen lymph glands in humans.

In summary, the use of castor oil for swollen lymph glands is primarily justified by traditional and anecdotal evidence rather than strong scientific validation. Further research would be needed to substantiate these traditional claims with rigorous clinical data.
