yerba/potassium

Minerals content (Fe, Ca, Mn, Mg, Na, K, Zn and Cu) of the leaves of Paraguayan yerba mate (Ilex paraguariensis, S.H.) as well as of commercial products has been determined by atomic absorption spectrophotometry. Considerable amounts of iron and calcium and remarkably high content of magnesium and

The study aimed to determine the content of selected elements: sodium, potassium, copper, zinc, iron, manganese and active ingredients such as phenolic acids and tannins in teas containing Yerba Mate and Rooibos cultivated in various areas. The study material comprised six samples of Yerba Mate teas

The influence of agronomic variables (light intensity, age of leaves, and fertilization type) on the content of macronutrients and micronutrients (potassium, calcium, sodium, magnesium, manganese, iron, zinc, and copper) of tea leaves was assessed by acid digestion, followed by flame atomic

We report the case of a subcutaneous hyalohyphomycosis of a 24-year-old man, a rural worker with an ulcerative lesion in the right leg of approximately one year duration. It was caused by traumatic implantation of a yerba mate branch. The diagnosis was made by direct microscopic examination with 20%
