cryptonite!
The opposite of kryptonite, which weakens Superman, is often considered to be a substance called "sunstone" or the effects of yellow sunlight. In the Superman lore, exposure to yellow sunlight enhances his powers rather than diminishing them. Thus, while kryptonite is harmful, yellow sunlight serves as a source of strength and vitality for Superman.

The Giant S is an illusion to fool Non. Although it appears to have substance it fades away. It seems to me that Superman thought the best way to beat them was to out think them. If you recall he also creates several duplicates of himself as well. This is not to say that he gained new powers but that he used the home field advantage.

Kryptonite is the debris from the planet Krypton and it contains radiation.
Kryptonite is the only known substance that can weaken and harm Superman, as it is radioactive remnants from his home planet, Krypton. Exposure to kryptonite can drain Superman of his powers and make him vulnerable.
Antihistamines block the release of histamine, a substance that causes allergic reactions.
Doh! He's from the planet Krypton, even though he's allergic to kryptonite.
No. An allergic reaction is the body's way of responding to a foreign substance, or an antigen.
An allergen is any substance that may cause an allergic reaction. So if an individual has an allergy to penicillin then penicillin is the stimulus for that individuals allergic reaction and PCN is an allergen but only for that individual. So any substance including nuts, pollen and drugs can act as an allergen. The key point is that allergens will only cause an allergic reaction in a person whose body perceives that substance as foreign but not for the general population.
Yes, it is possible to have a delayed allergic reaction to a substance or medication. This type of reaction may occur hours or even days after exposure to the allergen. It is important to seek medical attention if you suspect you are experiencing a delayed allergic reaction.
Pollen
No, you cannot make yourself allergic to something. You either are highly allergic, mildly allergic, sensitive, or non-allergic to any substance. Chronic exposure by sensitive people to allergens by actually help to build immunity to the allergen itself.
It is possible to be allergic to almost any substance. Only a doctor can tell you for sure, through proper testing.
Allergen
