# Huo Xiang (Agastache rugosa) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/huo-xiang **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-19 **Evidence Score:** 4 / 10 **Category:** Traditional Chinese Medicine **Also Known As:** Agastache rugosa, Korean Mint, Wrinkled Giant Hyssop, Patchouli, Pogostemon cablin, Indian Mint, Purple Giant Hyssop ## Overview Huo Xiang (Agastache rugosa) is a traditional Chinese medicinal herb containing pulegone as its primary bioactive compound. It traditionally treats digestive dampness conditions, though no human clinical trials have validated its health benefits. ## Health Benefits • No clinically validated health benefits - no human clinical trials identified in the research • Traditional use for digestive dampness conditions - evidence quality: traditional use only • Contains compounds with potential antihistamine properties (pulegone) - evidence quality: preliminary/chemical analysis only • Shows coagulation activity in isolated compound studies - evidence quality: preliminary/in vitro only • Used traditionally to harmonize [digestion](/ingredients/condition/gut-health) and relieve summer heat dampness - evidence quality: traditional use only ## Mechanism of Action Huo Xiang contains pulegone, a monoterpene ketone that may exhibit antihistamine activity through H1 receptor antagonism. The herb's volatile oils potentially modulate digestive function by affecting smooth muscle contractions in the gastrointestinal tract. Traditional mechanisms involve resolving dampness and harmonizing the middle jiao according to TCM theory. ## Clinical Summary No human clinical trials have been conducted on Huo Xiang specifically. Current evidence is limited to traditional use documentation and preliminary chemical analyses identifying bioactive compounds. Laboratory studies have characterized pulegone content and potential antihistamine properties, but these findings have not been validated in human subjects. The evidence quality remains at the traditional use and preliminary chemical research level. ## Nutritional Profile {"macronutrients": {"fiber": "Not specifically quantified in existing literature", "protein": "Not specifically quantified in existing literature"}, "micronutrients": {"vitamins": "No specific vitamins quantified in existing literature", "minerals": "No specific minerals quantified in existing literature"}, "bioactive_compounds": {"pulegone": "Present, specific concentration not quantified", "other_volatile_oils": "Includes compounds like menthone and limonene, specific concentrations not quantified"}, "bioavailability_notes": "The bioavailability of these compounds in humans has not been studied extensively, and their effects are primarily based on traditional use and preliminary chemical analysis."} ## Dosage & Preparation No clinically studied dosage ranges are available as no human trials have been conducted. The herb appears in traditional TCM formulas like Huo Xiang Zheng Qi Wan, but specific dosing is not quantified in the research. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Safety data for Huo Xiang is limited due to lack of clinical studies. Pulegone, the primary active compound, may cause hepatotoxicity in high doses based on studies of related plants. Potential interactions with antihistamine medications may occur due to similar mechanisms. Pregnancy and breastfeeding safety has not been established through clinical research. ## Scientific Research No human clinical trials, randomized controlled trials (RCTs), or meta-analyses specific to Agastache rugosa were identified in the provided research. The available studies focus solely on phytochemical isolation, genomic analysis, and documentation of traditional uses rather than clinical efficacy data. ## Historical & Cultural Context In traditional Chinese medicine, Huo Xiang has been used for centuries to transform dampness in the spleen, harmonize the middle burner, stop vomiting, and relieve exterior dampness or summer heat conditions. It is a key ingredient in the classic TCM formula Huo Xiang Zheng Qi San/Wan, traditionally prescribed for gastrointestinal dampness conditions. ## Synergistic Combinations Other TCM digestive herbs, ginger, citrus peel, magnolia bark, atractylodes ## Frequently Asked Questions ### What is pulegone in Huo Xiang? Pulegone is a monoterpene ketone compound found in Huo Xiang that provides its characteristic aroma. This compound has demonstrated potential antihistamine properties in preliminary studies through H1 receptor antagonism. ### Are there any clinical studies on Huo Xiang? No human clinical trials have been identified for Huo Xiang specifically. Current evidence is limited to traditional use documentation and basic chemical analyses of its bioactive compounds. ### How does Huo Xiang work for digestion in TCM? In Traditional Chinese Medicine, Huo Xiang is believed to resolve dampness and harmonize the middle jiao (digestive system). It traditionally treats conditions like nausea, vomiting, and digestive discomfort attributed to dampness patterns. ### Is Huo Xiang safe to take daily? Safety for daily use has not been established through clinical research. The pulegone content may pose hepatotoxicity risks in high doses, though safe dosage ranges have not been clinically determined. ### Can Huo Xiang interact with antihistamines? Potential interactions may occur due to pulegone's antihistamine-like properties, which could theoretically enhance or interfere with antihistamine medications. Clinical interaction data is not available, so caution is advised. ### Is Huo Xiang safe during pregnancy and breastfeeding? There is insufficient safety data on Huo Xiang use during pregnancy and breastfeeding, and it should be avoided in these populations as a precaution. Traditional use does not replace evidence-based safety testing in pregnant or lactating women. Consult a healthcare provider before using Huo Xiang if you are pregnant, planning pregnancy, or breastfeeding. ### What is the typical dosage range for Huo Xiang supplements? Traditional Chinese Medicine typically uses 6–12 grams of dried Huo Xiang herb per day, often prepared as a decoction or added to herbal formulas. Modern supplement forms vary widely in concentration and extract ratio, so follow the manufacturer's recommended dose on the product label. Dosing should be individualized based on formula composition and practitioner guidance. ### How does Huo Xiang compare to other aromatic digestive herbs like Peppermint? Both Huo Xiang and Peppermint are aromatic herbs traditionally used for digestive support, but Huo Xiang is specifically associated with drying dampness in TCM while Peppermint is often used for cooling and relieving gas in Western herbalism. Huo Xiang contains pulegone similarly to some mint species, though the concentration and traditional applications differ. Neither herb has robust clinical trial evidence, so traditional use patterns rather than clinical proof typically guide their application. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
