Asthma (Tamaka Shwasa)

Asthma is a chronic inflammatory disorder of the airways in which various inflammatory cells and mediators play an important role. The persistent inflammation makes the airways highly sensitive (airway hyperresponsiveness), causing them to react excessively to different environmental stimuli. This leads to inflammation of the bronchial lining, contraction of the bronchial smooth muscles, narrowing of the airways, and difficulty in breathing.

Types of Asthma

Based on the factors that trigger the disease, asthma is broadly classified into two types.

1. Extrinsic (Allergic/Atopic) Asthma

This is the most common form of asthma and usually begins during childhood or early adulthood. Individuals often have a personal or family history of allergic conditions such as allergic rhinitis, eczema, or urticaria. Exposure to allergens commonly triggers symptoms.

2. Intrinsic (Non-Allergic/Idiosyncratic) Asthma

This type generally develops later in adulthood and is not associated with a personal or family history of allergies. Skin allergy tests are usually negative, and serum IgE levels remain normal. In many cases, symptoms appear following viral upper respiratory tract infections and may be associated with chronic bronchitis or nasal polyps.

Common Causes and Triggers

Several factors can precipitate or worsen asthma attacks, including:

• Allergies and eczema (atopy)

• Family history of asthma

• Pollen, dust mites, feathers, and animal dander

• Certain medications

• Cigarette smoking

• Air pollution

• Cold air and fog

• Vigorous physical activity

• Emotional stress

• Recurrent upper respiratory tract infections

Common Symptoms

Asthma is characterized by recurrent episodes of:

• Wheezing

• Breathlessness

• Chest tightness

• Persistent cough, especially at night or early in the morning

Tamaka Shwasa

In Ayurveda, asthma is closely correlated with Tamaka Shwasa, one of the five types of Shwasa Roga, diseases affecting the Pranavaha Srotas (respiratory channels).Among The word 'Tamaka' means darkness, referring to the intense distress experienced during severe breathlessness.

According to Ayurveda, the disease develops due to the aggravation of Vata and Kapha doshas. Aggravated Vata moves upward abnormally, while Kapha obstructs the respiratory passages, leading to difficulty in breathing.

Clinical Features of Tamaka Shwasa

Patients may experience:

• Difficulty in breathing (dyspnoea)

• Wheezing with crackling sounds

• Productive cough with sputum

• Chest discomfort

• Rhinitis with nasal discharge

• Sweating over the forehead

• Dryness of the mouth

• Swelling around the eyes

Symptoms usually worsen while lying down, during cold, cloudy or rainy weather, and in the early morning. Patients often feel more comfortable in a sitting position and may obtain temporary relief after drinking warm water, hot fomentation, or expectoration of sputum.

Ayurvedic Causes (Nidana)

Vata Aggravating Factors

These include:

• Consumption of cold foods and drinks

• Dry and rough foods

• Irregular meal timings

• Exposure to cold winds

• Excessive physical exertion

• Carrying heavy loads

• Excessive sexual activity

• Suppression of natural urges

Kapha Aggravating Factors

These include:

• Heavy meals

• Overeating

• Eating before the previous meal is digested

• Oily and unctuous foods

• Cold foods and beverages

Special Types of Tamaka Shwasa

Pratamaka Shwasa

When Tamaka Shwasa is accompanied by fever and fainting due to Pitta involvement, it is termed Pratamaka Shwasa.

Santamaka Shwasa

When Pratamaka Shwasa progresses further with a sensation of being engulfed in darkness during severe respiratory distress, it is known as Santamaka Shwasa.

Ayurvedic Management

Since Tamaka Shwasa is primarily a Vata-Kapha disorder, treatment aims to relieve acute attacks, prevent recurrence, and strengthen the respiratory system.

During Acute Attacks (Vega Kaleena Chikitsa)

Management may include:

• Snehana (oleation)

• Swedana (sudation)

• Vamana (therapeutic emesis)

• Dhoomapana (medicated inhalation)

Between Attacks (Avega Kaleena Chikitsa)

The treatment focuses on preventing recurrence through:

Nidana Parivarjana

Avoidance of all triggering and aggravating factors.

Samshodhana

Purification therapies such as Vamana and Virechana in suitable patients with predominant Kapha and Vata.

Samshamana

Internal medications that promote digestion, reduce Kapha, pacify Vata, and clear the respiratory channels. This approach is especially useful for children, older adults, and individuals who are not suitable candidates for purification therapies.

Brimhana and Rasayana Chikitsa

Repeated asthma attacks can gradually weaken the body's tissues (Dhatu Kshaya). Therefore, Brimhana therapy helps restore strength and nourishment, while Rasayana therapy enhances immunity, improves respiratory health, and reduces the recurrence of attacks.

Commonly Prescribed Ayurvedic Medicines

Depending on the patient's condition and the physician's assessment, commonly used formulations include:

• Sitopaladi Churna

• Talisadi Churna

• Agastya Haritaki Rasayana

• Kanakasava

• Vasarishta

• Haridra Khanda

• Dashamoola Kwatha

• Yashtimadhu Churna
