Herbs in ClearLungs Immune

Elderberry Fruit

Elderberry is a part of TCM as well as traditional European folk medicine. Its dark berries contain quercetin, a common extract in natural over-the-counter medicines because of its potential to support the body's natural, healthy state free from excess inflammation. It also contains significant amounts of vitamins A and C.

Olive Leaf Extract

Native to the Middle East, the olive tree has stood as a symbol in Western culture for thousands of years. Today scientific evidence shows the components of the olive leaf can help support a healthy immune response and considering the olive tree’s well-known ability to resist disease this makes sense. Its leaves are full of antioxidants, which show promise in supporting cardiovascular health as well.

Isatis Root Extract

Isatis root has been used in both TCM and Ayurvedic medicine for thousands of years. From the same plant as the dye for indigo, clinical studies have shown it to have potential to support the body's natural, healthy state free from excess inflammation, as well as a positive immune response, though further research is still needed. This is becoming a more common TCM herb and is used as a bitter herb for the liver and stomach meridians.

Andrographis Extract

Believed to clear heat and resolve toxicity, Andrographis is a common herb in TCM. Scientists around the globe have explored the potential for this herb to support immune function and the body's natural, healthy state free from excess inflammation, as well as its capacity to encourage the body's ability to fight free radicals.

Mullein Leaf

This herb has been used in various global traditions, and each one uses it to soothe the respiratory tract. Whether applied as a warm poultice, taken as a tea, or infused into a steam bath, the goal to manage airway health has always been the same. It was also used to ward off Native American spirits, as a dye for Roman women's clothing, and as a wick for lamps in ancient Greece.

Dong Quai Root

The phytochemicals within this plant are said to help support the body in white blood cell production. Renowned for its ability to encourage a positive immune response, Dong Quai Root has many wellness-promoting properties. Studies show it may help the body's ability to naturally dilate bronchioles to support open airways and encourage circulation to the lungs and respiratory system. In addition, it contains small amounts of vitamins A and E, biotin, carotene, and pantothenic acid.

Ophiopogon Root

Ophiopogon helps restore the human system's essential moisture and bodily fluids. It’s especially effective in bringing moisture back to the lungs and helping the body to balance normal mucus levels. Exceptional for treating external conditions that may dry and irritate lungs, such as smoke, dust, inversion, winter weather, insufficient humidity, etc.

Poria Fungal Body

Poria, which contains multiple vitamins and other nutrients essential to healthy cardiac function and blood circulation, is used in TCM to rid the body of excess "dampness." In the process, it helps balance electrolytes and revitalizes the spleen, which is responsible for storing half of the body's white blood cells (monocytes). This supports the immune system and helps it function properly.

Chinese Asparagus Root

Chinese asparagus root is called the "Queen" of herbs due to its wide range of effective properties. It’s particularly known as a lung tonic recognized for its potential to help support the body moisten and gently cleanse the lungs and respiratory tissues.

Chinese Skullcap Root

Chinese Skullcap is one of the most widely used herbs in Chinese medicine, particularly as support for the bronchioles and the larger respiratory system. Skullcap contains compounds that support the body's natural, healthy state free from excess inflammation, encourage natural immune function, and promote healthy urine flow, bile production, and more.

Gardenia Fruit

In traditional Chinese medicine, Gardenia is most used to "drain fire," i.e., to help support normal temperature and the body's natural, healthy state free from excess inflammation. Gardenia is also commonly used to help maintain healthy nasal pressure, calmness within the body, and muscle relaxation.

Luo Han Guo Fruit

Luo Han Guo Fruit is used in TCM for respiratory and lung support. High in Vitamin C, it’s also recognized in TCM as a "guiding herb" to direct other herbs towards the upper body, especially the respiratory system.


Platycodon is included in this formula for its ability to focus support on the chest, help phlegm management throughout the system, aid respiratory and sinus health, and support loosening and comfort in the lungs.

Tangerine Mature Peel

Tangerine peel serves to balance and regulate Qi (chi), i.e. air, gas, and energy flow throughout the body. The tangerine peel helps provide Qi energy to each organ throughout the human system, especially to the lungs.

White Mulberry Root Bark

Commonly used in traditional Chinese herbal combinations for its ability to help the body build respiratory function, and for its properties as a tonic for the liver, kidney, and lungs.

Zhejiang Fritillary Bulb

Most used to support the body's ability to deal with conditions relating to the heart and lungs. Specifically, it’s used to help balance mucus, avoid system stagnation, nourish the lymphatic system, and support overall cardiovascular function.

Schisandra Fruit

Known for its extraordinary adaptogenic properties including the ability to potentially help normalize and balance multiple human systems, this herb promotes oxygen supply for the cells, supports the body's immune system, protects against stress, and builds stamina.

Chinese Licorice Root

One of the most widely used herbs in TCM, licorice is used to stimulate, support, and harmonize gland function. It helps support the adrenal glands and immune system, energy production, and aids cellular removal of toxins. Scientific evidence exists indicating its ability to reinforce the body's natural, healthy state free from excess inflammation. Licorice root contains glycyrrhizin, a chemical compound that maintains the body's ability to block enzymes that lower the prostaglandin levels responsible for mucus production. It also acts as a guiding herb to enhance the activity of other key ingredients.

Availablend™ Bioavailability Complex

Availablend™ is RidgeCrest Herbals' patented blend containing several ingredients that have been recognized for their digestive and bioavailability-supporting* properties. It includes ginger root, black pepper, habanero pepper, and Sichuan pepper. *Clinical studies have not been done on Availablend™ linking it to increased bioavailability.


Is ClearLungs Immune safe to take with other herbs or medications?

Yes. ClearLungs Immune is very safe with no known contraindications. It is safe to take with any other herb or medication.

Should I take this product if I am pregnant or nursing?

While many customers have taken ClearLungs safely while pregnant and nursing, there are two ingredients (Dong Quai and Licorice Root) that in larger doses may be contraindicated. Therefore, we recommend that if you’re pregnant, consult with a healthcare provider familiar with the effects of herbal remedies before taking this product.

Will ClearLungs Immune make me jittery or nervous?

No. ClearLungs Immune does not have any stimulants and won’t make you feel jittery or nervous. If you struggle with these symptoms on a regular basis, we recommend trying Adrenal Fatigue Fighter™ or Anxiety Free™.

Will ClearLungs Immune keep me awake at night/prevent me from sleeping?

No. There are no stimulants in ClearLungs Immune and it shouldn't affect your sleep. If you struggle with falling or staying asleep, we recommend trying DreamOn™ Zen.

Are there any side effects from taking ClearLungs Immune? (Risks?)

No. ClearLungs Immune has no known side effects and is made of gentle herbs that aren’t known to create any negative issues. However, as everyone is different, if a reaction does occur, we ask that you contact our customer service department so we can track it.

Is ClearLungs Immune habit-forming?

No, ClearLungs Immune cannot cause dependence. Will the licorice in ClearLungs Immune raise my blood pressure? It’s not likely. While European licorice has been shown to raise low blood pressure in large doses, Chinese licorice has not been shown to have the same effects and is not used for that purpose in herbal medicine. Our ClearLungs® Immune formula contains a small amount of Chinese licorice, while it takes over 400mg of European licorice to effectively raise blood pressure. You should always consult with your physician before making changes to any blood pressure regimen.

What’s the difference between AirwayClear™ and ClearLungs®?

The main difference lies in the traditional Chinese medicine ideas of cooling and warming formulas. Cooling formulas are designed to calm and relax, while warming formulas are intended to stimulate the body. AirwayClear™ is a cooling formula, designed to promote a healthy inflammatory response and cool irritation, helping the airways to relax and soothe. ClearLungs is designed to stimulate the lungs to help promote healthy mucosal response to irritation while maintaining healthy airways. You can take AirwayClear and ClearLungs together.


All ClearLungs formulations are most effective when paired with a healthy lifestyle:

  • Losing weight will positively impact respiratory function
  • Sufficient rest and exercise
  • Removing inflammatory foods from the diet
  • Avoidance of allergens and dust, and from warm, humidified air in winter
  • Washing hands frequently - especially during the winter season - to avoid transfer of flu and cold viruses
