Your Guide to Plum Dragon Liquid Herbal Extracts for Immune Support

Chilly morning runs. Ski season in full swing. Hibernating at home. No matter what winter looks like for you, there’s one thing most of us have in common this time of year: our immune systems are under more pressure.

The exposure to cold, wet weather and a lack of sunlight mean our bodies have to work harder to stay well. That’s where smart seasonal support comes in. 

Plum Dragon’s liquid herbal extracts offer simple ways to stay ahead of seasonal illnesses. Whether you’re feeling run down, are around sick people often or just want to stay resilient, these formulas have your back. But which ones are right for you?

Why Immune Support Liquid Extracts Should Be Your Winter Ally

Before we dive into our range of immune support supplements, it’s good to know why we recommend herbal extracts this time of year. 

It’s simple – when it comes to preventative habits, ease matters. Liquid tinctures are fast, easy to take and absorb quickly. No brewing or prepping, just a few drops in a glass of water, juice or tea and you’re set.

Unlike one-size-fits-all remedies, Plum Dragon’s extracts are based on traditional herbal formulas, each with its own purpose and method of restoring balance. You can choose the one that fits your current needs or use a combination for extra support.

Liquid Herbal Extract Formulas for Immune Support 

When your immune system needs real backup, these formulas are your best bet. They combine time-tested herbal combinations that work together to fight off pathogens, ease your symptoms and support immune recovery. Each one is crafted to target either a different stage of illness or a specific presentation (for example, heat symptoms or cold symptoms).

Wen Bing Defense 

For early-onset illnesses with signs of heat

This formula is based on traditional Chinese medicine principles for clearing wind-heat – that cold that comes on quickly with a scratchy throat, fever or swollen glands. It blends cooling and clearing herbs like honeysuckle, forsythia and isatis to support a strong immune response at the first sign of symptoms.

Wen Bing Microbiota Defense

For stubborn illnesses and gut health support   

This version of Wen Bing is a slightly broader-spectrum formula. While it still supports immune response, it goes a step further by focusing on gut and microbial health (an essential part of long-term immune strength). It includes antimicrobial herbs like huang lian and huang bai, immune-modulating mushrooms and botanicals like olive leaf and chicory root to help rebalance gut flora and clear deeper heat. Ideal for when you're recovering from something that just won’t quit, or if you’re prone to chronic infections and gut troubles. 

Shanghan Lun Defense

For cold or damp-type illnesses with added Lung support

Do your colds typically present with more chills, clear and runny mucus, and fatigue? This formula focuses on warming up cold and dampness while strengthening the lungs and digestive system. It includes warming herbs like cinnamon twig and perilla leaf, along with qi-boosters like astragalus and codonopsis. A good choice for those who tend to feel cold easily or get sick after exposure to windy or damp weather!

SurviveAll 

For potent respiratory support and chronic or complex infectious illnesses 

SurviveAll is a modern blend of both Eastern and Western herbs based on the Buhner protocols for viral illnesses. It’s designed to help your body fight off acute illness by supporting the respiratory system and targeting microbial infections with herbs like lomatium, licorice, osha and red root. 

Nei Wei Qi 

For daily immune maintenance and prevention

Nei wei qi is the body’s internal defensive qi, and it’s considered the foundation of immune resilience in TCM. This gentle yet effective formula focuses on nourishing and regulating this system long-term, using just three powerful anti-inflammatory herbs: isatis root (ban lan gen), Chinese skullcap (huang qin) and licorice root (gan cao). This one is great for daily preventative use if you’re prone to getting sick easily or recovering from chronic illness.

CytoSupport 

For overactive immune system responses 

CytoSupport is a unique formula designed to help the body’s immune system resist a cytokine storm. Rooted in both traditional Chinese medicine and the research of herbalist Stephen Buhner, it strengthens nei wei qi (internal defensive qi) and helps regulate immune overactivity. Key herbs like Chinese skullcap and licorice inhibit viral attachment to cells, while lomatium prevents these pathogens from replicating. Added support comes from herbs like astragalus, cordyceps and pueraria to provide balance and restore energy.

Liquid Herbal Extract Single Herbs for Added Support  

While the formulas above offer a foundation of immune support, single-herb tinctures give you the power of more targeted action or preventative daily use. These concentrated extracts are ideal for customizing your herbal routine based on your constitution, lifestyle or specific seasonal needs. Use them on their own or to enhance a larger formula.

Huang Qin Liquid Extract 

For reducing inflammation and supporting immunity 

Huang qin is traditionally used to clear heat, dry dampness and calm inflammatory processes in the lungs and digestive tract. It supports the body when immune responses run hot, helping prevent inflammation from spiraling out of control. From a scientific standpoint, huang qin contains flavonoids like baicalin and baicalein, which have been studied for their antiviral, antibacterial and anti‑inflammatory effects. Add this on to immune formulas when you need extra support for heat signs like fever, sore throat or inflammation.

Osha Root Liquid Extract 

For powerful respiratory support 

Osha has a strong effect on the lungs and respiratory system. Energetically, it helps dispel external pathogens (like cold and damp) while warming and protecting the airways. This makes it a go-to extract for combating cold weather or early cold symptoms. Research also shows that Osha has antimicrobial and antiviral properties, can help clear mucus and eases breathing. As a single herb, it pairs well with other immune formulas when respiratory support needs a boost.
