Bai La (White Beeswax) possesses the nature of astringency and firmness, serving as an essential herb in external medicine. It promotes tissue regeneration, alleviates pain, knits bones, and reconnects tendons. For tonifying deficiency, it is combined with Cortex Albiziae (Hehuan Pi) to prepare Changrou Gao (Flesh-Growing Ointment), which yields miraculous effects. However, its efficacy when taken orally alone remains untested, whereas Cortex Albiziae has been proven effective through personal use.

Ricini Semen (Banshenzi) has a strong astringent nature; it can draw out pus and expel toxins, making it another essential herb. Spina Gleditsiae treats carbuncles and sores, whether unruptured or ruptured, by penetrating and guiding pus to the ulcerated area. Among the various ointment formulas described in "Shenyi," none surpass this one in efficacy.
Regarding Qi and Blood stagnation, it often stems from weakness in Ying Wei (Defensive and Nutritive Qi), which fails to circulate and dissipate. How can Liqi Yin (Qi-Flowing Decoction) be reused, thereby exacerbating deficiency? Furthermore, the quantity of Qi and Blood varies among meridians: the Pericardium, Bladder, Small Intestine, and Liver meridians are rich in Blood but deficient in Qi; the Sanjiao (Triple Burner), Gallbladder, Kidney, Heart, Spleen, and Lung meridians are deficient in Blood but rich in Qi. After the age of forty, Yin Blood declines daily. If abscesses occur in meridians deficient in Blood, or if pulse and symptom manifestations are insufficient, treatment should primarily focus on tonification and restoration.
Zhu Danxi stated: In Swelling Ulcers (Zhongyang), where both interior and exterior are obstructed, the primary approach should be Tuo Li Biao San (Supporting the Interior and Dispersing the Exterior)—that is, using Qi- and Blood-tonifying herbs combined with moving and dispersing agents, rather than purely attacking methods. If swelling and pain are severe, accompanied by irritability and a large pulse, acrid-warm agents should not be used for swelling ulcers, nor even for ulcerated wounds. For every patient, one must differentiate the meridian involved, the state of Qi and Blood, the distance of the location, the age of the patient, the constitution's deficiency or excess, the influence of Seven Emotions, and seasonal appropriateness. It is common to see practitioners indiscriminately using Liqi Yin and Shixuan San (Ten-Accumulations Powder) to treat all nodular swellings, leading to frequent failures.
Generally, diseases have primary and secondary aspects, and treatment requires flexibility. Treating the primary aspect causes secondary symptoms to recede naturally; employing flexibility allows one to transcend rigid conventions. Adhering strictly to routine practices inevitably leads to critical danger. Moreover, indiscriminately using attacking agents disturbs the various meridians. Therefore, Danxi said: When a sore originates in a specific meridian, one should seek the cause within that meridian alone and avoid disturbing other meridians.
