What is Sang Ji Sheng? Are Hu Ji Sheng, “Ji Sheng” and Sang Zhi the same?
Official Sang Ji Sheng (桑寄生) is the dried leafy stem of Taxillus chinensis. The pharmacopoeial name is Taxilli Herba. Hu Ji Sheng is the leafy stem of Viscum coloratum, a separate monograph Visci Herba: bitter-neutral, similar functions but different taste and botanical source—not an automatic equal swap. A prescription that only says “Ji Sheng” must name Sang Ji Sheng or Hu Ji Sheng. Sang Zhi is the young mulberry twig: dispels wind-damp and benefits the joints—it is not mistletoe. Stems parasitic on poisonous hosts (such as oleander) must not be used as medicine. Write Sang Ji Sheng.
What are the TCM properties and traditional uses of Sang Ji Sheng?
According to the Chinese Pharmacopoeia, Sang Ji Sheng is bitter, sweet and neutral, enters the Liver and Kidney channels, and acts to dispel wind-damp, supplement Liver and Kidney, strengthen sinew and bone, and calm the fetal origin. It is used for wind-damp bi pain, lumbar-knee soreness and softness, sinew-bone lack of strength, flooding and spotting or heavy menses, pregnancy spotting, restless fetus, and dizziness. Bitter-sweet-neutral, supplementing while dispelling—suited to Liver-Kidney insufficiency with wind-damp or insecure fetal origin, not to damp-heat red swollen hot bi used as a lone supplement.
Does Sang Ji Sheng need special processing or decoction? How do you choose it versus Hu Ji Sheng?
Cut segments go in the pot, or they may be steamed then dried; first- or late-decoction is not required. South and southwest China commonly use Sang Ji Sheng; north and northeast often use Hu Ji Sheng. Functions are close but the pharmacopoeia lists them separately—write the full name. Calming the fetus and supplementing Liver-Kidney lumbar-knee soreness more often use Sang Ji Sheng.
What is the usual dosage? Can it be drunk daily as a blood-pressure or low-back tea?
The pharmacopoeial decoction dose is 9–15 g. It is not a four-season “mistletoe blood-pressure tea.” Damp-heat redness and swelling and exterior excess heat only stagnate further when supplemented. Liver-Kidney insufficiency and restless fetus need a practitioner to set dose and course; do not use anonymous “Ji Sheng” as tea.
What are the contraindications? Can it be used in pregnancy?
Use caution as a lone supplement in damp-heat bi with redness and swelling and in Spleen-Stomach damp encumbrance; forbid material from an unknown or poisonous host. The pharmacopoeia lists pregnancy spotting and restless fetus among its indications—it is a classic fetus-calming herb and must be pattern-differentiated by a practitioner, not self-dosed in large amounts. Use caution in Kidney deficiency with heat and short red urine. Stop if vomiting and diarrhea appear.
Can Sang Ji Sheng dispel wind-damp, strengthen the lumbar-knees and calm the fetus?
It can help Liver-Kidney insufficiency. Wind-damp lumbar-knee aching joins Angelica pubescens, Eucommia and Achyranthes in Du Huo Ji Sheng Tang. Restless fetus and pregnancy spotting join Cuscuta, Dipsacus and Ass-hide glue in Shou Tai Wan. It supplements Liver-Kidney while dispelling wind-damp and calming the fetal origin—not a specific for every arthritis, every low-back pain or every threatened miscarriage. High fever with red swollen joints and heavy vaginal bleeding are emergencies.
Can Sang Ji Sheng be drunk daily as a blood-pressure, anti-aging or pregnancy tea?
Liver-Kidney insufficiency may enter a formula or a short tea; damp-heat and unknown hosts must not. “Mistletoe lowers pressure and anti-ages” does not replace cardiology and antenatal care. Supplementing Liver-Kidney and calming the fetus should name Sang Ji Sheng and a 9–15 g dose, and distinguish it from Hu Ji Sheng.
How do you choose among Sang Ji Sheng, Hu Ji Sheng, Du Huo, Du Zhong and Xu Duan?
Taxillus is bitter-sweet-neutral: dispels wind-damp, supplements Liver and Kidney, strengthens sinew and bone and calms the fetal origin—supplements while dispelling. Viscum is bitter-neutral: similar functions, different source, common in the north. Angelica pubescens is acrid-bitter and slightly warm: dispels wind-damp and unblocks bi to stop pain—leans to lower-jiao wind-cold-damp, strong to dispel and weak to supplement. Eucommia is sweet-warm: supplements Liver-Kidney, strengthens sinew and bone and calms the fetus—clearer warm supplementation. Dipsacus is bitter-acrid and slightly warm: supplements Liver-Kidney, strengthens sinew and bone, knits fracture and stops flooding. Wind-damp with Liver-Kidney vacuity favors Sang Ji Sheng and Du Huo; pure vacuity lumbar-knees favor Du Zhong and Xu Duan; calming the fetus often pairs Sang Ji Sheng with Xu Duan. They may be combined; all are wrong as pure warm supplementation in damp-heat hot bi, and the mistletoe source must be identified.
Which herbs is Sang Ji Sheng combined with? What are the representative formulas?
Wind-damp bi pain with dual Liver-Kidney vacuity joins Angelica pubescens, Gentiana macrophylla, Eucommia, Achyranthes and Angelica sinensis in Du Huo Ji Sheng Tang. Restless fetus joins Cuscuta, Dipsacus and Ass-hide glue in Shou Tai Wan. Write Sang Ji Sheng; do not mix it with Hu Ji Sheng or Sang Zhi.
How do you choose and store Sang Ji Sheng?
Choose slender tender stems, red-brown or gray-brown, leafy, faint in odor and astringent in taste. Thick, hollow, leafless, moldy, moth-eaten and unknown-host lots are inferior. Store dry against moths. Buy pharmacopoeial Sang Ji Sheng; do not replace fetus-calming Liver-Kidney supplementation with an equal weight of Hu Ji Sheng or anonymous “Ji Sheng.”
