I understand that PEs are out of scope -- eliquis is there for preventing clots; however, the PEs sat in this patient's lungs for 10 months. When there is a case of chronic PEs, there is a high risk of interstitial fibrosis due to chronic inflammation. How can herbs be used to support the lungs? herbal antiinflammatories/ antioxidants etc. We are trying to get this patient off of oxygen -- if her lungs get fibrotic, she will need oxygen for the remainder of her life. Without supplemental oxygen her oxygen sat is 90%. Again, tongue w/ yellow, thick coat -- heat signs. Crack in st/spleen area. Constitutionally the patient is vata -- thin, nervous, anxious, high strung. I know we have gone over many herbs which are liver or renoprotective? what herbs would be best lung tonics? Prince Seng perhaps?
