Asthma – Symptoms, Causes, Treatment. Home Remedies for Asthma

Bronchial asthma represents a complex, chronic inflammatory condition of the respiratory tract that primarily affects the bronchi—the critical conduits linking the trachea to the alveolar sacs where gas exchange occurs. This disease is characterized by recurrent episodes of symptom exacerbation that can significantly impair an individual’s capacity to perform routine occupational, social, and personal activities. The diagnosis of asthma relies predominantly on clinical observation, with the occurrence of an acute asthmatic attack during diagnostic procedures serving as a particularly compelling indicator. Equally invaluable are the details obtained through a comprehensive medical history, which may include a record of allergic rhinitis, recurrent urticarial skin reactions, and distinctive nocturnal symptoms such as wheezing, persistent coughing, or transient apnea. It is important to note that asthmatic exacerbations may manifest either abruptly—developing within mere minutes or hours—or gradually, progressing over several days, which in severe cases can culminate in dangerous hypoxia and, in extreme instances, even life-threatening complications.

Based on the inflammatory profile, asthma is classified into two primary forms: **atopic (allergy-mediated) asthma** and **bronchoconstrictive (non-allergic) asthma**, which differ in both their pathophysiological underpinnings and the age groups most commonly affected. **Atopic asthma** predominantly emerges during early childhood and is characterized by an **exaggerated synthesis of immunoglobulin E (IgE)** in response to specific allergens. Contemporary theories suggest that **excessive hygiene practices in early life**—particularly during the first few years—may limit the immune system’s exposure to environmental microbes and antigens, thereby **impeding the development of immunological tolerance** to potential allergens later in life. The core pathophysiological mechanism involves an **antigen-antibody interaction on the surface of mast cells**, triggering degranulation and the release of proinflammatory mediators (e.g., histamine, leukotrienes). These substances induce **bronchial smooth muscle constriction** and mucosal edema, culminating in airway narrowing. Conversely, **bronchoconstrictive (non-atopic) asthma** is more prevalent in adults and is **not associated with elevated IgE levels or a familial history of allergies**. Its onset is frequently preceded by **viral upper respiratory tract infections**, which may initiate a chronic inflammatory state. This manifests later as **episodes of dyspnea, wheezing**, and heightened bronchial hyperresponsiveness to non-specific triggers such as cold air or tobacco smoke.

The etiology of asthma remains an active subject of scientific inquiry, as it has yet to be definitively elucidated. Current evidence suggests that the disease arises from the interplay of a multifaceted array of determinants, among which allergic hypersensitivity reactions to exposure to specific environmental antigens play a predominant role. The pathomechanism of asthmatic exacerbations is characterized by the activation of inflammatory cascades and dysregulation of immune responses, clinically manifesting as episodes of dyspnea, wheezing, and paroxysmal coughing of variable severity. The fluctuating concentrations of allergens in ambient air result in symptoms that may emerge intermittently, depending on seasonal variations, atmospheric conditions, or specific micro-environmental factors, thereby substantially complicating the identification of precise triggers. Equally significant are exogenous factors, including both passive and active tobacco smoke exposure, elevated levels of particulate matter (PM2.5 and PM10), chemical aerosols, grass and tree pollens, domestic animal dander (from dogs, cats, and rodents), and—less commonly—pharmacological intolerances to nonsteroidal anti-inflammatory drugs or beta-blockers. Psychosocial determinants also warrant consideration, as chronic oxidative stress, anxiety disorders, or depressive states may modulate bronchial reactivity via the hypothalamus-pituitary-adrenal axis, exacerbating smooth muscle contraction within the airways.

The cardinal clinical manifestations of bronchial asthma encompass a subjective sensation of breathlessness, paroxysmal coughing of varying severity, the pathognomonic expiratory wheezing, and an oppressive or constrictive discomfort within the thoracic cavity. During the prodromal phase of an asthmatic exacerbation, patients frequently report a mounting sensation of thoracic tightness accompanied by a dry, persistent cough. Progressive bronchial narrowing becomes clinically apparent through the emergence of distinctly audible rhonchi and sibilant breath sounds, accelerated respiratory rate, and phonatory difficulties stemming from compromised airflow dynamics. As the asthmatic episode intensifies, breath sounds may diminish in audibility—potentially becoming inaudible in cases of severe air trapping—an ominous sign necessitating urgent medical evaluation. In less conventional asthma phenotypes, such as exercise-induced asthma, symptomatic expression may be limited to recurrent coughing or dyspneic episodes that manifest exclusively during vigorous physical activity, with unremarkable findings on physical examination when the patient is at rest.

The primary therapeutic objective in managing bronchial asthma is to achieve sustained stabilization of pulmonary function while eliminating clinical symptoms entirely. A cornerstone of effective treatment is the patient’s proactive collaboration with the healthcare team, particularly the attending specialist physician. An indispensable condition for maintaining remission involves the systematic avoidance of all potential triggers, including tobacco smoke, household allergens such as dust mites or particulate matter, and high-intensity stressful situations. Routine follow-up visits and periodic diagnostic evaluations play a pivotal role in monitoring therapeutic progress. During acute exacerbations characterized by dyspnea, fast-acting rescue medications are administered, with dosage and type determined on an individualized basis by the physician. The foundation of anti-inflammatory pharmacotherapy consists of inhaled corticosteroids (ICS), which substantially enhance pulmonary ventilation and diminish airway hyperresponsiveness, thereby providing patients with rapid symptomatic relief. As second-line therapy, long-acting inhaled beta2-adrenergic receptor agonists (LABA) are introduced; their mechanism of action involves bronchodilation through relaxation of smooth muscle tissue and reduction of mucosal edema, with effects lasting approximately 12 hours. Furthermore, the impact of a balanced dietary regimen on overall respiratory system health and immune resilience must not be overlooked.

The dietary approach for individuals diagnosed with bronchial asthma should adhere to principles of a balanced, health-promoting diet, with emphasis on fresh plant-based foods. Of paramount importance are vitamin C-rich sources—a potent antioxidant that neutralizes free radicals and fortifies the body’s defenses against allergens. However, caution is advised when introducing new foods, as cross-reactivity may trigger allergic symptoms, particularly with citrus fruits. Equally vital are polyunsaturated omega-3 fatty acids with anti-inflammatory properties, along with specific spices and beverages that may enhance airway patency. Monitoring individual food tolerance—especially regarding highly allergenic products—is also critical.

A multitude of bioactive compounds present in everyday dietary sources may play a pivotal role in inhibiting the progression of bronchial asthma while substantially mitigating the severity of associated symptoms. Beyond the extensively discussed omega-3 fatty acids and ascorbic acid (vitamin C), particular attention should be directed toward food products with well-documented health-promoting properties, most notably raw honey—a substance prized not only for its culinary versatility and palatability but also for its centuries-long application in folk medicine as an adjunct to facilitate pulmonary ventilation. The topical administration of a minimal quantity of this natural preparation to the skin beneath the nasal vestibule may alleviate respiratory difficulties. Furthermore, in instances where excessive mucus secretion in the throat impairs swallowing, the use of fig leaf extract—renowned for its expectorant qualities—has demonstrated efficacy. Equally noteworthy is licorice root (*Glycyrrhiza glabra*), which, owing to its comprehensive pharmacological profile, occupies a prominent position among herbal supplements with therapeutic potential. Its broad spectrum of activity encompasses supportive treatment for diverse respiratory disorders, including chronic inflammatory conditions of the airways that characterize asthma.

For centuries, traditional herbal medicine has played a significant role in alleviating symptoms associated with bronchial asthma. Among the most frequently cited botanical remedies with potential adjunctive effects are: the leaves of ribwort plantain (*Plantago lanceolata*), the root of smooth licorice (*Glycyrrhiza glabra*), the inflorescences of small-leaved lime (*Tilia cordata*), the herb of common thyme (*Thymus vulgaris*), the leaves of peppermint (*Mentha × piperita*), the root of marshmallow (*Althaea officinalis*), and the fruit of Egyptian bishop’s weed (*Ammi visnaga*). The mechanism of action of these preparations is primarily based on bronchodilation, reduction of inflammatory processes, and facilitation of mucus expectoration. Due to the potential for interactions with conventional medications and individual contraindications, the incorporation of any herbal remedy into a therapeutic regimen should be preceded by a thorough consultation with a pulmonologist or attending physician, taking into account the patient’s complete medical history.
