Q I get influenza every year — can an immune tonic prevent the flu too?

A. Rather than blocking the flu virus itself, the more realistic benefit is milder symptoms when infected and faster recovery.

Q I am an elderly resident of Dong-gu, Incheon in my 70s — will a tonic still work at my age?

A. Immune tonics are fully effective even for patients in their 70s and above, and provide practical benefits for energy recovery and maintaining respiratory immunity.

Q I have rhinitis or asthma — can an immune tonic help with these respiratory conditions as well?

A. Since the root of rhinitis and asthma also lies in Lung Qi deficiency and Defensive Qi insufficiency, immune tonics can help alleviate symptoms.

Q Can I exercise while taking an immune tonic? Will it drain my energy instead?

A. Moderate aerobic exercise enhances the tonic’s effects, while excessive exercise consumes Qi and Blood and can have the opposite effect.

Q I work in Dong-gu, Incheon and frequently do overtime — does the tonic regimen need to be different in my case?

A. When overwork and sleep deprivation persist, the tonic’s effectiveness is halved. Supplementation in both timing and prescription composition is needed.

Q Will taking a tonic containing Astragalus or Ginseng for a long time cause excess heat or side effects in my body?

A. Taking tonics without considering individual constitution can cause heat sensations or digestive discomfort, so a diagnosis and prescription are essential.

A. Certain herbs are contraindicated during pregnancy, so you must inform your practitioner of your pregnancy status before receiving a prescription.

Q I take medication for hypertension or diabetes — can I take an immune herbal tonic at the same time?

A. Concurrent use is possible in most cases, but you must inform your practitioner of all medications you are currently taking.

Q How long can I expect the effects of an immune tonic course to last?

A. With consistent long-term management, the immune foundation stabilizes over a 2–3 year period and the frequency of seasonal colds decreases significantly.

Q I had shingles once — can an immune tonic help prevent recurrence?

A. Since recurrence of shingles is primarily caused by a decline in immune function, immune-strengthening tonics provide meaningful preventive benefit.

Q I catch a cold every season change — what is the Korean medicine explanation?

A. It is because deficient Lung Qi (肺氣) and Defensive Qi (衛氣, Wei Qi) cannot ward off external pathogenic factors.

Q I have had a weak respiratory system since childhood — is this a constitutional issue?

A. It is likely that your Lungs and Spleen-Stomach are constitutionally deficient from birth, but the acquired foundation can be sufficiently strengthened through proper care.

Q Are immune-boosting foods more effective when combined with herbal immune tonics?

A. Foods beneficial for the respiratory system such as bellflower root, pear, and ginger complement the tonic's effects, while cold foods and flour-based products hinder Lung Qi recovery.

Q Once I receive a tonic prescription, how long do I take it and when do I return for a follow-up?

A. Typically a 4-week prescription is given first to check progress, and 2–3 months is considered one full course.

A. Pediatric immune tonics are possible from around age 4 and above, and the prescription composition differs from that for adults.

Q What tests or diagnostic process are involved before starting an immune tonic course?

A. Lung Qi status and Spleen-Stomach deficiency are assessed through pulse diagnosis, abdominal palpation, and intake questioning before a prescription is given.

Q Does taking an immune tonic mean I will catch fewer colds, or recover faster when I do get one?
