Sap from an ash tree is a sticky, amber-colored liquid that is harvested in the early spring before the tree starts to produce leaves. The sap has a sweet, slightly bitter taste and a fragrant aroma. It is often used to make a variety of products, including syrup, wine, and even beer. In fantasy settings, sap from an ash tree may have magical properties, such as being used in potions or spells related to growth, regeneration, or fertility. The sap may also be considered a valuable commodity due to its scarcity or unique properties, and may be sought after by alchemists or other magic users.
