Butterbur (PA free)

Butterbur (PA Free) is a robust perennial herb belonging to the Petasites hybridus species, native to Europe, Asia, and North America, and traditionally used for centuries in herbal medicine as a powerful remedy for pain, inflammation, and spasms. The PA Free designation refers to the removal of pyrrolizidine alkaloids, naturally occurring compounds in the plant that can be harmful to the liver, making it safe for regular therapeutic use. Butterbur is most celebrated for its clinically validated effectiveness in preventing migraines, reducing their frequency and severity, and relieving allergic rhinitis and hay fever symptoms. It also exhibits powerful antispasmodic, anti-inflammatory, and bronchodilatory properties that support respiratory health and ease asthma symptoms.
