It's both fruit and vegetable.
Good source of iron, phosphorus, calcium, vitamins A and B, and excellent source of vitamin C.
Tomatoes are loaded for vitamin C, a potent antioxidant that mops up free radicals.
Tomatoes also contain lycopene, p-coumaric acid and cholorogenic acid, all possibly helpful in reducing cancer risks.
- Pulp and juice are mild aperient.
- Juice used for asthma and bronchitis.

• Lycopene / Hepatoprotective: Lycopene is considered a better antioxideant than other carotenoids. In a study on acute injury caused by oxidant carbon tetrachloride (CCl4), results showed that tomato juice, with its lycopene and ascorbic acid content, exhibited a strong effect on oxidative damage of CCl4 in rat liver.
• Lectins / Mucosal Immunogen: Lycospersicum esculentum lectins studies suggest it to be a potent mucosal immunogen, enhancing immune responses to antigens.
• Tomatoes in Gene Therapy: Jure Piskur et al from the Lund University, published study results suggesting the tomato gene could be of value in future treatment of brain tumors.
• Antimutagenic / Anticlastogenic: Study evaluated the combined effect of tomato and garlic against DBMA-induced genetic damage and oxidative stress in mijce. Results suggest a broad spectrum of antimutagenic and anticlastogenic effects may b e achieved through a combination of functional foods.

In The News
• Fruitflow / Antithrombotic / Aspirin Alternative: Study claims that Fruitflow, a tomato extract, can reduce the risk of blood clots, which can trigger heart attacks and strokes. Results of a human clinical trial compares Fruitflow with aspirin, with its ability to reduce platelet aggregation by 28% through three different biologic pathways (vs aspirin, 60% reduction, in a single pathway).
