Active Ingredient TCVM Actions
Xin Yi San combines Wind-dispersing, nasal-opening, and channel-unblocking herbs with Qi-tonifying and Damp-resolving agents to address both Wind-Cold and Wind-Heat nasal patterns and the underlying Wei Qi deficiency that allows Wind to invade:
- Xin Yi Hua (Magnolia biondii), Magnolia flower bud: The chief herb; opens the nasal passages, disperses Wind-Cold, and unblocks nasal stagnation; the primary nasal-opening herb in the formula.
- Cang Er Zi (Xanthium sibiricum), Cocklebur fruit: Opens the nasal passages, disperses Wind-Cold-Damp, and relieves nasal congestion and discharge; works with Xin Yi Hua as the classic nasal-opening pair.
- Bai Zhi (Angelica dahurica), Dahurian angelica root: Disperses Wind-Cold, opens the nasal passages, relieves pain, and dries Dampness in the nasal passages and sinuses.
- Gao Ben (Ligusticum sinense), Chinese lovage root: Disperses Wind-Cold, relieves pain, and supports the formula's Wind-Cold-dispersing action in the upper body and head.
- Chuan Xiong (Ligusticum chuanxiong), Sichuan lovage rhizome: Invigorates Blood, moves Qi, disperses Wind, and relieves pain; unblocks the channels in the head and nasal passages.
- Bo He (Mentha haplocalyx), Peppermint herb: Disperses Wind-Heat, clears the head and eyes, and opens the nasal passages for the Wind-Heat component of the pattern.
- E Bu Shi Cao (Centipeda minima), Centipeda herb: Disperses Wind-Cold, opens the nasal passages, and relieves nasal congestion and discharge; particularly effective for chronic nasal obstruction.
- Jiang Can (Bombyx mori, stiff), Stiff silkworm: Disperses Wind, resolves phlegm, and unblocks the channels, addressing the phlegm-Wind component of nasal stagnation.
- Huo Xiang (Pogostemon cablin), Patchouli herb: Transforms Dampness, harmonizes the middle Jiao, and supports the formula's Damp-resolving action in the nasal passages and sinuses.
- Huang Qi (Astragalus membranaceus), Astragalus root: Tonifies Spleen and Lung Qi, raises Wei Qi, and strengthens the body's defensive energy to reduce susceptibility to Wind invasion and support long-term nasal health.
Potential Drug Interactions
Xin Yi San contains Wind-dispersing and channel-unblocking herbs (Xin Yi Hua, Cang Er Zi, Bai Zhi, Chuan Xiong) alongside a Qi-tonifying herb (Huang Qi) and a Wind-Heat-clearing herb (Bo He) that may interact with certain medications. Pets on prescription medications should use this formula under veterinary supervision, as herb-drug interaction research in dogs and cats remains limited.
Medication categories warranting extra caution include anticoagulant or antiplatelet medications, immunosuppressive medications, and pets managing multiple concurrent prescriptions. Use with caution in pregnant patients. Your veterinarian can determine appropriateness based on your pet's condition, current medications, and laboratory results.

Frequently Asked Questions
What conditions is Xin Yi San used for in TCVM?
Xin Yi San is most commonly recommended for dogs, cats, and horses with TCVM patterns of Wind-Cold or Wind-Heat invading the nasal passages and Lung, causing nasal congestion, discharge, sneezing, or chronic nasal obstruction. Holistic veterinarians frequently prescribe it for pets with environmental sensitivities, recurrent nasal congestion, or allergic rhinitis-type patterns rooted in Wind invasion and nasal stagnation. The manufacturer lists no contraindications for this formula, but caution is advised in pregnant patients.
How is Xin Yi San administered, and what are the recommended doses?
Dosing varies by species, body weight, and health condition; your authorizing veterinarian will determine the appropriate dose following a TCVM evaluation. For dogs and cats using 0.5g concentrated capsules, the general guideline is one capsule per 20 to 40 lbs of body weight twice daily. For small dogs and cats under 10 lbs, one 0.2g capsule once daily is typical. For the 90g concentrated powder, the dose for dogs and cats is 0.1g to 0.25g per 10 to 20 lbs twice daily, with the included small scoop holding approximately 0.3g. For horses, the standard dose is 3g (approximately 2.5 large scoops) twice daily, with the large scoop holding approximately 1.2g.
How long does it take to see results with Xin Yi San?
Response time varies depending on the individual pet, the severity of the Wind invasion and nasal stagnation pattern, and the format used. Many pet owners begin to notice improvements in nasal congestion, discharge, and respiratory comfort within 1 to 3 weeks of consistent use. The manufacturer recommends use for up to 3 months. Regular follow-up with your holistic veterinarian is recommended to monitor progress and adjust dosing as needed.
Can Xin Yi San be combined with other TCVM formulas or medications?
Xin Yi San is sometimes used alongside other TCVM formulas as part of a comprehensive respiratory or immune support protocol, but combination use should always be guided by your authorizing veterinarian. Use with caution in pregnant patients. If your pet is on prescription medications, particularly anticoagulants or immunosuppressants, your veterinarian will evaluate whether Xin Yi San is appropriate given your pet's full health picture and current treatment plan. The manufacturer lists no contraindications for this formula.
