Soap, "anti-bacterial soap", and hemorroid
Soap is made by applying strong alkaline solution (such as sodium hydroxide) to fat. Its molecule has two ends: one is hydrphilic (water soluble) and the other is hydrophobic (water insoluble and therfore oil absorbing). It is this amphiphilic property that make it a detergent which can drag the dirt/oil off your clothes. All detergent are like this!
Interestingly enough, cell membrance also consists of amphiphilic molecule (outer surface is water soluble and the middle is water insoluble). By the same property, detergent can de-stablize cell membrance. That's why all detergents are anti-bacterial.
That's why before antibiotics penicillin was born, soap is the only weapon we got to fight against bacteria. If you got open wound, clean it up with soap and water, you will be in good shape. Bandage doesn't hurt either for its protection.
Anti-bacterial soap is a complete marketing hype since soap itself is anti-bacterial.
Hemorroid is a very prevalent medical condition caused by swelling of veins. It gets worse when you eat spicy food or have irregular defecation habit. Most of the times, it does not need medical attention. It can be self-treated by applying soap with your finger during the shower after each defecation (shitting). By having this habit, most hemorroids can be self-cured.

Very interesting article. I thought soap was used to clean dirt and oil. I didn't know that it is good to kill bacterials too. It reminds me a lot of other products, such as Safeguards, Dawn, Softsoap, etc., that use antibackterial as their marketing strategy.
