Asthma Plant (Euphorbia hirta), also known as Tawa-Tawa in the Philippines or Dudhali in Ayurveda, is a common tropical weed with a remarkable history in traditional medicine.1 Its primary historical use is reflected in its common name, being a staple remedy for respiratory and pulmonary conditions.2

The plant contains a rich mix of flavonoids (like Quercitrin), triterpenoids, and polyphenols that contribute to its broad-spectrum therapeutic benefits.3


I. 🌬️ The Respiratory System (Primary Use)

  1. Bronchodilator Effect: This is the most studied claim. Extracts of E. hirta have been shown in animal models to exert a dose-dependent bronchodilator effect, meaning they help relax the bronchial tubes and open airways.4
  2. Anti-Asthmatic & Anti-Cough: Used traditionally to relieve symptoms of asthma, chronic bronchitis, hay fever, and spasmodic coughs.5 The relaxation of the bronchial muscles helps reduce tightness and congestion.6
  3. Antihistaminic & Anti-Allergic: Flavonoids in the plant help suppress the release of certain inflammatory mediators (like histamine), offering anti-allergic support for irritated airways.

II. 🦠 Infection, Inflammation, and Wounds

  1. Antimicrobial & Antiviral: Extracts possess strong antibacterial and antifungal activity against various pathogens, including E.7 coli and Staphylococcus aureus, supporting its traditional use against infections.
  2. Antidiarrheal & Antispasmodic: Quercitrin, a key compound, has demonstrated potent antidiarrheal activity by modulating fluid absorption in the colon.8 The plant also has antispasmodic effects, helping to soothe colic and intestinal discomfort.9
  3. Wound Healing & Skin Ailments: The plant’s latex is traditionally applied topically to cuts, warts, boils, and fungal infections to promote healing and stop microbial spread.10
  4. Anti-Inflammatory & Analgesic: Aqueous extracts exhibit analgesic (pain-relieving) and anti-inflammatory properties, used for treating muscle pain, headaches, and general systemic inflammation.11

III. 💧 Metabolic and Reproductive Support

  1. Diuretic and Electrolyte Balance: Extracts have been shown to induce significant diuresis (increased urine output), helping the body flush excess fluid and toxins.12
  2. Blood Sugar Regulation: Studies suggest the plant has hypoglycemic effects, potentially aiding in the management of blood sugar levels.13
  3. Antimalarial: Historically used as an antimalarial agent, with some studies showing inhibitory activity against P. falciparum parasites.14
