Introduction
Chicken gizzard lining (Nei Jin) can serve as an adjunctive therapy for kidney stones. It promotes digestion and facilitates the elimination of stones. Clinically, it demonstrates relatively good efficacy in treating various types of calculi, including kidney stones and gallstones, and exhibits definite therapeutic effects. However, as a single-herb remedy, its therapeutic effect is somewhat limited, and treatment duration tends to be prolonged. Therefore, for active management of kidney stones, comprehensive treatment combining Nei Jin with other medications is recommended.
Kidney stones are a common and recurrent condition, primarily resulting from the progressive accumulation of crystalline substances and organic matrix within the kidneys over time—eventually forming hard, stone-like deposits. As stone size increases, kidney function may become impaired, and physical discomfort may arise due to mechanical compression of renal tissue. Targeted interventions can be employed to reduce stone volume. So, can *Gallus gallus* gastric lining (Chick’s Gizzard Lining, or “Ji Nei Jin”) treat kidney stones? Let’s explore this further.
Can Ji Nei Jin Treat Kidney Stones?
Ji Nei Jin may serve as an adjunctive therapy for kidney stones. As a traditional Chinese herbal medicine, Ji Nei Jin possesses digestive-enhancing and litholytic properties. Clinically, it demonstrates relatively favorable efficacy in treating various types of calculi—including kidney stones and gallstones—and offers measurable therapeutic benefits. However, its effectiveness as a monotherapy is limited, and treatment duration tends to be prolonged. Therefore, optimal management of kidney stones requires comprehensive, integrative approaches—such as combining Ji Nei Jin with other herbs like *Lysimachia christinae* (Jin Yin Cao), *Lygodium japonicum* (Hai Jin Sha), and *Arca subcrenata* (Wa Leng Zi)—to formulate individualized, syndrome-differentiated herbal prescriptions, thereby enhancing overall therapeutic outcomes.
Knowledge Expansion: Treatment Options for Kidney Stones
1. General Management
Increase daily fluid intake; consume foods that promote calcium absorption and those rich in calcium—such as fish, shrimp, and crab. Diets abundant in minerals and trace elements also support stone dissolution and facilitate spontaneous passage of stone fragments via urine. For health maintenance, limit intake of high-oxalate foods—including tofu, celery, soybean skin, potatoes, and grapes.
2. Ureteroscopy (URS)
Ureteroscopy is a minimally invasive surgical procedure involving insertion of a ureteroscope through the urethra and bladder into the ureter and kidney to fragment stones. Its primary advantages include minimal tissue trauma and high stone fragmentation efficiency. However, access to calyceal regions—particularly the lower calyx—may be technically challenging.
3. Extracorporeal Shock Wave Lithotripsy (ESWL)
ESWL delivers focused shock waves from an external source directly onto the stone, progressively fragmenting it into fine sand-like particles that are subsequently excreted in the urine. ESWL is most effective for renal pelvis and mid-to-upper calyceal stones measuring 5–20 mm in diameter. Contraindications include pregnancy, distal urinary tract obstruction, coagulopathy, renal failure, acute urinary tract infection, severe cardiac arrhythmias, and excessively large stone burden.
The above provides an overview addressing the question: “Can Ji Nei Jin treat kidney stones?” We hope this information proves helpful.
