    What does it do?

    Helps You Breathe Easier

    You could be standing in the most verdant, oxygen-rich lush rainforest on Earth. But when you can't breath deeply, you may as well be trapped in a coffin because you feel like you're suffocating. It's an awful feeling, one that you can't wait to be rid of. Unfortunately, heavy congestion and phlegm can keep you off balance for several days or even weeks at a time. And when you're short of breath, you can't exercise, much less concentrate for several hours at a time at work. All you want to do is lay in bed; if only you had that luxury.

    To overcome heavy congestion and cough, most people turn to over-the-counter cold remedies or medications. However, if you're seeking an herbal alternative, Breathmooth™ is a traditional Chinese medicine (TCM) remedy that may help open the airways so you can breathe more effortlessly and smoothly.

    Signature formula improves upon classic TCM cough remedy

    If you're not an expert in TCM, finding the appropriate formula for symptoms related to colds can be challenging. That's because in TCM, there are several different cold types. Breathmooth may be especially beneficial for the type of cough known in TCM as Wind-Cold.

    Wind-Cold invasions may result in one or more of the following: a lingering cough; shortness of breath; rapid breathing; rattling cough; a desire to spit when coughing or a heavy feeling in the chest and/or body.

    Breathmooth is our signature formula that builds upon several classical formulas to alleviate any cough type that presents with white or clear phlegm and shortness of breath.

    How does Breathmooth work?

    Breathmooth transforms and/or dispels Phlegm as well as Wind. Breathmooth also may offer relief because of its ability to diffuse Lung Qi.

    Jie Geng (Platycodon Root) ventilates the Lungs and dispels phlegm. Bai Qian (Cynanchum) descends Qi and expels phlegm. Qian Hu (Hogfennel Root) disperses wind, clears heat, directs Qi downward and transforms phlegm. Bai Bu (Stemona Root) moistens the Lungs and moves Qi downward and stops coughing. Jing Jie (Schizonepeta Herb) releases the exterior and disperses wind. Jiang Ban Xia (Pinellia) dries dampness and transforms phlegm. Bei Mu (Thunberg Fritillary Bulb) clears heat, transforms phlegm and arrests coughing. Fang Feng (Siler Root) releases the exterior and dispels wind and dismisses dampness.

    Sang Bai Pi (Mulberry Root Bark) drains the Lungs and is one of the most commonly used TCM herbs for opening the airways. Bai Gao (Ginkgo Nut) also is a famous TCM herb for opening the airways because it astringes the Lungs and expels Phlegm. Zi Su Zi (Perilla seed) also opens the airways by redirecting rebellious Lung Qi downward. In addition, it dissolves phlegm to stop coughing. The last herb in the formula, Ting Li Zi (Lepidium Seed), also opens the respiratory airways by draining the Lungs.

    Does Research Support Breathmooth?

    A TCM formula that includes 6 Chinese herbs used in Breathmooth (Jie Geng, Jing Jie, Bai Bu, Fang Feng, Bei Mu and Bai Qian) was well-tolerated and appeared to have benefits in supporting the respiratory health in a Hong Kong randomised double-blinded placebo-controlled trial.1. A meta analysis of Zhi Sou San, a popular Chinese herbal remedy for cough, concludes the remedy offers significant benefits. Compared with Western medicine, it significantly improved the total effective rate and the pulmonary function in terms of FEV1. Four of the seven herbs (Jie Geng, Jing Jie, Bai Bu and Bai Qian) in Zhi Sou San are a part of Breathmooth. 2

    How do I use it?

    The standard dosage for Breathmooth™ is 6 tablets each time, taken 2 to 3 times daily with or before meals. One bottle lasts users 12 to 17 days. The dose may be doubled for a quicker and stronger response as needed (e. g., in an acute phase). Consult your practitioner for precise dosage recommendations based on body weight and other factors.

    Breathmooth™ has a mild action and therefore it usually takes time before its effects become apparent. It may take one month or more before symptoms begin to improve. An initial course of treatment is suggested as 6 bottles taken at the full dose.

    1. Avoid oily, spicy food while taking the product.
    2. Consult your herbalist or physician before use if you are taking other medicines.
    3. Only to be used by children under adult's direction.

    Breathmooth™ (Ke Chuan Pian) is rated 4.7 out of 5 by 12.
    Rated 5 out of 5 by from Miracle! I originally was given this remedy by the acupuncturist I was seeing. It arrested congestion and cough that usually results in bronchitis or pneumonia and weeks of medications and missed work. I use it when I feel I am getting ill with tightness and cough. It may not prevent it 100% of the time but it shorten the time I am sick and relieves the cough and congestion. I have offered it to family and friends and they are amazed at the great results too. I try to always have this along with Cold Signoff and Coughoff in my house!

    Rated 5 out of 5 by from Very good product I am a TCM practitioner and bought the product for my girlfriend's asthma bronchitis. I must say it works quickly and effectively. I also use NasoPass for her sinusitis problems which actually was one of the the primary causes of her asthma. It works very well as well especially when combined with acupuncture. In addition I recently helped my girlfriend get rid of a spate of egzema rash on the skin by using XiaoFeng Pian. Egzema rash was gone almost completely only after 1 bottle of this product. I recommend the products and will keep using them for sure.

I take 5 pills twice a day to help with a tight chest and weezing. It did not take me a full bottle to take effect, it helped pretty quick. Great product. I use Lung Vigor as well.
