Immunity/Respiratory Health

Q I catch the flu every year—can a tonic prevent even the flu?

A. Rather than blocking the flu virus itself, it's more realistic to expect the tonic to ease symptoms and speed recovery if you do get infected.

Q I'm an elderly resident of Incheon Dong-gu in my 70s—would a tonic still be effective for me?

A. Tonics remain effective even for those in their 70s and beyond, offering real benefits for energy recovery and maintaining respiratory immunity.

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

A. Since the root of rhinitis and asthma also lies in Lung Qi deficiency and lack of Defensive Qi, an immune tonic may help ease symptoms.

Q Is it okay to exercise while taking a tonic? Won't it drain my energy instead?

A. Moderate aerobic exercise enhances the tonic's effect, while excessive exercise depletes Qi and blood and can backfire.

Q I work in Incheon Dong-gu and frequently work overtime at night. Does that change how I should take a tonic?

A. Prolonged overwork and lack of sleep reduce the tonic's effect. Adjustments are needed in timing and formula composition.

Q If I take a tonic with Astragalus or Ginseng for a long time, won't I develop excess heat or side effects?

A. Taking it without considering your constitution can cause heat sensations or digestive discomfort, so it must be prescribed after a proper diagnosis.

Q I'm pregnant or breastfeeding—can I take an immune tonic?

A. Since some herbs are contraindicated during pregnancy, you must disclose your pregnancy status and receive a proper prescription.

Q I'm taking blood pressure or diabetes medication—can I also take an immune tonic?

A. Combined use is possible in most cases, but you must inform your Korean medicine doctor of your full medication list first.

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

A. With consistent management, the immune foundation stabilizes over 2-3 years, and seasonal cold frequency drops noticeably.

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

A. Since shingles recurrence is mainly caused by lowered immunity, an immune-boosting tonic can genuinely help with prevention.

Q I catch a cold every time the seasons change—what's the Korean medicine explanation?

A. It's because your Lung Qi (肺氣) and Defensive Qi (衛氣) are too weak to block external pathogens.

Q I've had weak respiratory health since childhood—is this a constitutional issue?

A. It's likely a constitution with congenitally weak Lung and Spleen-Stomach function, but it can be strengthened well through acquired care.

Q Are foods good for immunity effective alongside Korean medicine tonics?

A. Foods good for the respiratory system, such as balloon flower root, pear, and ginger, complement tonic effects, but cold foods and flour-based foods hinder Lung Qi recovery.

Q Once I get a tonic prescribed, how long do I take it, and when should I come back?

A. Typically, you take a 4-week prescription, return for a check-up, and a full course is considered 2-3 months total.

Q I'm worried about my child's immunity—can children also receive immune tonics? From what age?

A. Immune tonics for children are possible from age 4 and up, with a different formula composition than adults.

Q What kind of examination or diagnostic process happens before starting an immune tonic?

A. Pulse diagnosis, abdominal diagnosis, and detailed history-taking are used to assess Lung Qi status and Spleen-Stomach weakness before prescribing.

Q Does Korean medicine tonic really help immunity? Is there evidence?

A. Herbs used in immune tonics, such as Astragalus, have shown immune-modulating effects in modern studies, including NK cell activation.

Q Does taking a tonic mean I'll catch fewer colds, or that I'll recover faster when I do catch one?

A. Both effects can be expected, with the prevention of repeated infections typically appearing first.
