A variety of herbal plants have been used worldwide to remedy various diseases. The healing aspect of herbal plants have been accepted in many cultures and have been known as alternative medicine. Some herbs may consist of pharmaceutical ingredients suitable to treat certain cases such as stomach acidity or ulcers. Our aim was to verify the claim that some herbal "folk" plants can be used as an alternative for neutralizing the stomach acidity. Therefore, the purpose of this research was to test selected herbal plants for anti acid efficacy and estimate the acid-neutralizing capacity by addition of excess acid, followed by back-titration of the excess acid with sodium hydroxide. The anti acid capacity of the herbs was compared with that of anti acid tablets containing magnesium hydroxide and calcium carbonate as the active ingredient.

Olive trees, fruits and oil play an essential part of the Mediterranean life, culture, economy and diet. Taking good care the trees, fruits and oil is one of the main concerns to the farmers in Palestine, because of the impact on the final quality of olives. Proximity of the olive tree to streets frequented by high traffic diesel trucks influences the overall health of the trees that affects quality of the product. Exhaust emission from diesel engines releases by product called Polycyclic Aromatic Hydrocarbons (PAH's), which are known to be carcinogenic agents. The purpose of the project is to analyze olive fruits and olive oil for the presence of such chemicals using Solid-Phase Extraction (SPE) followed by Thin Layer Chromatography (TLC) and U.V. Florescence for rapid Detection. Interesting results were obtained and showed that most olive oil samples tested negative, while the olive fruits tested positive for PAH's.
