Origin & History
Ash Tree Sap Concentrate, often referred to as 'manna,' is derived from the exudate of Fraxinus species, particularly Fraxinus ornus (Manna Ash) and Fraxinus excelsior (European Ash). Historically harvested in the Mediterranean region, notably Sicily, the sap solidifies into a sweet, crystalline concentrate. It is valued for its mild laxative properties and as a natural sweetener in traditional herbal medicine.
“Ash tree sap, known as 'manna,' has been harvested since ancient Greek and Roman times, particularly in Sicily, for its medicinal and culinary applications. Its biblical reference as divine sustenance underscores its historical significance. This traditional practice continues today, valuing manna as a gentle natural laxative and sweetener.”Traditional Medicine

Frequently Asked Questions
What is Ash Tree Sap Concentrate?
Ash Tree Sap Concentrate, also known as manna, is a natural exudate harvested from Fraxinus ornus (Manna Ash) trees, primarily in Sicily. It solidifies into sweet, crystalline flakes rich in mannitol, a sugar alcohol with gentle osmotic laxative properties.
How much Ash Tree Sap Concentrate should I take for constipation?
For mild laxative effect, adults typically use 5-15 grams dissolved in warm water or milk, taken on an empty stomach. Start with a lower dose to assess tolerance. Excessive intake above 20 grams may cause bloating or diarrhea due to mannitol's osmotic action.
How does Ash Tree Sap compare to other natural laxatives?
Unlike stimulant laxatives such as senna, manna works as a gentle osmotic laxative by drawing water into the intestines, making it better tolerated and suitable for sensitive individuals including children. However, clinical research specific to manna is limited compared to well-studied laxatives like psyllium or polyethylene glycol.
