Background: Respiratory diseases are often caused by the lack of lung energy flow manifested in shortness of breath, generalized weakness, extreme fatigue, and even reluctance to speak. This study evaluates four plants for the respiratory system from a pharmacological perspective. Thyme
(Thymus vulgaris L.), sage (Salvia officinalis L), peppermint (Mentha piperita L.) and hyssop (Hyssopus officinalis L.) are discussed from a modern pharmacological perspective, including their scientific name and family, the used parts, active ingredients, therapeutic properties, pharmacological effects, indications, and available medicines. Botany features such as plant shape, description, distribution, and cultivation, including suitable places, range, and cultivation
method, are further investigated.Methods: Information such as the used plant parts, therapeutic properties, pharmacological effects, indications, and medicine forms were gathered through data collection, library resources, written articles, and reference books. Other information such as plant shape and description, planting method, time, and more were obtained by planting seedlings in a research departments affiliated with the Kohgiluyeh and Boyer-Ahmad Agriculture and Natural Resources Research and Education Center.Results: These medicinal plants, such as Salvia officinalis, contain “Terpene”, “Selenium” and other substances, and clean the sinuses and relieve respiratory and lung disorders. Due to its high “polyphenols” content, this plant protects lung tissue against bacteria which may pose risk and cause infection in the respiratory system. Respiratory diseases are often caused by low energy manifested in short inhalation and exhalation, generalized weakness, extreme fatigue, and even reluctance to speak. Natural substances and plants are useful for treating respiratory problems. Conclusion: Due to its significance for sustaining human life, even minor respiratory disruptions such as smoking, vitamin deficiency, and other factors cause diseases such as seasonal allergies, bronchitis, tuberculosis, asthma, pulmonary edema, lung problems, pneumonia, and lung cancer.
