Lingzhi has the effects of tonifying qi and calming the mind, relieving cough and asthma (stopping coughing and calming wheezing), and can be used to alleviate symptoms such as insomnia, palpitations (rapid heartbeat, often accompanied by panic attacks), dreaminess, and coughing and wheezing due to lung deficiency. However, the active ingredients of ganoderma lucidum in water are limited, and it is generally difficult to achieve a therapeutic effect. Ganoderma lucidum is sweet in flavor, flat in nature, and enters the heart meridian, which can calm the mind, benefit the heart qi, and replenish the heart blood, and can be used to treat heart and soul instability, such as tiredness and fatigue, insomnia, dreaminess, forgetfulness, and palpitations, etc. Ganoderma lucidum can be used alone, or together with Paeoniae lactiflora, Angelica sinensis, and jujube nut. Ganoderma lucidum enters the lung meridian and can tonify lung qi. It can be used alone or together with Astragalus, Schisandra chinensis and Radix et Rhizoma Ginseng in the treatment of coughing and wheezing due to lung deficiency. Due to the limitation of drug dosage and compounding, the effect of ganoderma lucidum in water is limited, and it is recommended to follow the doctor’s advice to choose the way of decoction. If the above discomfort occurs, it is recommended to consult a doctor in time, and it is not advisable to use medication on your own to avoid adverse consequences.
