Helia alba

Helia alba is widely used as a bitter-tasting digestive tea in the Peruvian Andes, where infusions or decoctions of the leaves are taken after meals to ease stomach cramps, flatulence, and loss of appetite. In Amazonian Peru, the Shipibo‑Conibo people also prepare leaf infusions for digestive complaints, while in the mestizo communities of the Pasco region infusions of the aerial parts are drunk for mild stomach pain and as a “stomach tonic.” Along the Madre de Dios river, healers prepare leaf decoctions for the same purpose and sometimes add a small amount of the decoction to local aguardiente as a stomachic. The same bitter-tasting leaf infusions are recorded in Cusco and the Selva Central as a home remedy for sluggish digestion and mild nausea. These reports appear in field ethnographies and regional floras, including those of Macbride, Schultes, and more recent collections by Cabieses and Jørgensen and Sagástegui in the northern Andes.

For a simple bitter digestive tea, steep 5–8 g of dried Helia alba leaves in 250 mL of nearly boiling water for 10–12 minutes, then strain. Drink a warm 150 mL cup after the main meal, up to twice daily. bitterness is expected and often valued. In some communities, a short, mild decoction of the leaves (5 g simmered in 250 mL of water for 8–10 minutes, cooled slightly) is preferred as a stomachic, while others use a fresh leaf maceration (about 1 part fresh leaves to 5 parts water) left to stand at room temperature for several hours and taken in small doses. A tincture is less common, but a 1:5 45% ethanol leaf tincture can be macerated for 14 days and taken in small measures of 20–30 drops as needed, if the solvent is locally available. Do not exceed 3–4 cups daily; avoid if you are pregnant or nursing, and stop if heartburn or stomach upset worsen. Individuals with known sensitivity to Asteraceae should use caution. Bitter tonic uses are associated with postprandial discomfort rather than with acute infection.

The bitterness and reported digestive activity fit the species’ known profile of phenolic acids, coumarins (including scopoletin), and a volatile fraction rich in 1,8‑cineole, alpha‑ and beta‑thujone, camphor, and alpha‑pinene. These constituents are commonly present in Asteraceae and provide a chemically plausible basis for carminative and stimulant effects on digestion, although modern pharmacological work on Helia alba itself remains sparse. These chemicals have been identified in related genera and in Helia specimens examined in the Americas.

Today the plant is still collected locally in central and northern Peru and sold in herbal stalls as a digestive bitter. While research on Helia alba’s specific pharmacology and safety is limited, field notes and regional floras continue to record its bitter tea, and small-scale artisan tinctures are sometimes prepared by practitioners who value its taste and traditional indications.
