Da Huang enters which channels?

Da Huang enters which channels?

• A. HT, ST, LV, LI
• B. LU, HT
• C. HT, KD, LV
• D. ST, LV

Answer: (A)

Da Huang’s effects travel through channels that align with its strong purgative and heat-clearing actions. Its main actions target the GI tract, so it clearly enters the Large Intestine and Stomach channels to purge stasis and clear heat there. It also moves blood and helps resolve liver-heat or liver-stagnation, which is why the Liver channel is involved. Some authorities extend its channel reach to the Heart region because its heat-clearing and blood-moving effects can influence chest or heart-area conditions, so the Heart channel is sometimes listed as part of its entries. Together, HT, ST, LV, and LI reflect the herb’s broad channel reach used in clinical formulas, which is why this option is considered correct in this context.
