Chinese Chive (Allium tuberosum), known as "Jiu Cai" in traditional Chinese medicine (TCM), has a long history of use in Chinese herbal practices. It is typically used for conditions related to digestion, yang deficiency, and as a general tonic. There is some traditional literature suggesting its use in promoting blood circulation and resolving blood stasis, which are concepts in TCM that may loosely relate to conditions involving inflammation or poor circulation, such as phlebitis (inflammation of a vein). However, these uses are based on TCM theory rather than modern biomedical mechanisms or clinical trials.

Despite its traditional use for "promoting circulation," there is little direct evidence from classical texts specifically mentioning Chinese Chive as a remedy for phlebitis. Furthermore, in the scientific literature, there are no robust studies or clinical trials demonstrating that Chinese Chive is effective in treating or supporting phlebitis. The evidence for using Chinese Chive in this context is therefore primarily traditional, with a very low evidence rating, and should not be interpreted as endorsement for its use in clinical practice for this condition.
