Costus-root (Tu-mu-xiang) – The Herb Used in Traditional Systems to Support Respiratory Comfort and Inner EaseCostus-root (Tu-mu-xiang) is the traditional Chinese medicine name for the dried root of Inula helenium L., an aromatic herb that has long been part of traditional East Asian herbal practices. The herb is traditionally used in combinations designed to support respiratory comfort and to maintain ease in the chest and abdomen. Unlike some related species, costus-root (Tu-mu-xiang) is particularly known for its cooling and soothing properties.Traditional Understanding in TCM SystemsWithin traditional Chinese medicine, costus-root (Tu-mu-xiang) is described as an herb with aromatic, slightly bitter and moistening properties. In the TCM theoretical framework, it acts on the so‑called Liver, Lung and Spleen meridians. According to this traditional description, costus-root (Tu-mu-xiang) supports normal breathing and helps transform fluid accumulation in the lungs. It is traditionally used to promote comfortable breathing sensation and to regulate normal mucus secretion in the airways.In TCM formulas, costus-root (Tu-mu-xiang) is seen as an herb that helps transform "Dampness" and "Phlegm" – traditional concepts connected with normal mucous membrane health and lung health. It is also used in situations described as "dampness in the lungs" or "uncomfortable breathing" – TCM patterns traditionally associated with sensations such as chest tightness, more frequent coughing and wetter mucus.Botanical Composition and ResearchCostus-root (Tu-mu-xiang) contains over 70 bioactive compounds, including inulin (40–50%), sesquiterpenes, flavonoids, phenolic compounds and essential oils. A particularly important group of active constituents are the sesquiterpene lactones, including alantolactone and iso‑alantolactone, and related sesquiterpenes such as costunolide.Modern scientific research shows that these natural components possess diverse biological activities. Studies demonstrate that costus-root (Tu-mu-xiang) extracts:Can help regulate normal inflammatory reactions in the airwaysPossess antimicrobial activity against certain bacteria and fungiCan support normal mucus secretion and fluid balance in the airwaysPossess antioxidant activity, protecting cellular structuresCan help support normal immune responseAre traditionally used in lung health systems in various culturesCurrent studies focus on how the active components can contribute to normal respiratory comfort and health of mucous membranes. Research suggests that alantolactone and related sesquiterpenes can act at multiple levels – an approach that aligns with the traditional, multifaceted application of the herb.Traditional Applications – TCM ContextIn traditional TCM formulas, costus-root (Tu-mu-xiang) is classically used in situations described as:Uncomfortable coughing sensation or dry coughFluid accumulation in the lungs (moist cough)Chest tightness or sensation of oppression in the chestCompromised breathing or uncomfortable breathing sensationSupporting normal mucus productionSupporting normal lung function and respiratory comfortGeneral fluid comfort in chest and abdomenThese are traditionalist descriptions that form part of the TCM thinking system and must not be equated with medical diagnoses in the sense of European medicinal product law.Cooling and Moisture‑Balancing CharacterCostus-root (Tu-mu-xiang) is traditionally used especially in seasons when normal moisture levels in the airways need optimal support – often during periods of humid climate or when respiratory comfort needs particular attention. Its cooling character makes it suitable for people with a tendency toward heat in the airways.Well‑being and Daily UseCostus-root (Tu-mu-xiang) is valued by modern users as part of a conscious wellness routine focused on respiratory and lung comfort, especially when they wish to support their natural breathing ease or during periods of seasonal transitions. The herb works optimally in balanced herbal mixtures, combined with a varied diet, regular movement and moments of relaxation.Many users see Costus-root (Tu-mu-xiang) as part of a long‑term approach to respiratory comfort and overall well‑being – as a supportive element in traditional routines, alongside professional guidance and regular medical care when needed.Important Distinction: Tu-mu-xiang vs. Other "Mu Xiang"There are several herbs with "Mu Xiang" in their name, but with different botanical sources and properties:Tu-mu-xiang (Inula helenium): cooling, for respiratory supportMu Xiang (Aucklandiae Radix): warm, for digestionChuan Mu Xiang (Saussurea costus): warm, for abdominal comfortThese three have different traditional applications and properties.Important Note for the ConsumerThis product is a dietary supplement and not a substitute for medicines or professional medical advice. If you have persistent or serious complaints, you should always consult a doctor or health expert. TCM terms such as Dampness, Lungs, Phlegm and Breathing are system concepts that form part of a traditional thinking system and must not be directly equated with anatomical structures or disease explanations in modern medicine.
