L-arginine cream is a substance used primarily to enhance libido in females. The amino acid L-arginine has been shown to increase blood flow to tissues in the body and is a major factor in building proteins used by various cells and organs. Increased blood flow can help with sexual arousal, especially in those with a lagging sex drive. Newer uses for L-arginine cream involve increasing blood flow to the feet of those with diabetes.
Most forms of L-arginine cream meant for increased sexual arousal are applied directly to the clitoris. During naturally induced arousal more blood goes to the sex organs. For a woman, the primary organ responsible for arousal is the clitoris, which is packed with nerve endings. Those with sexual dysfunction may not get this rush of blood naturally, but using topical cream can cause increased flow through artificial means.
There are also more recent studies showing that L-arginine cream may be beneficial to diabetics by causing more blood flow to enter the lower extremities. Poor circulation is a problem for many people living with diabetes, and it can lead to painful and potential life threatening conditions like ulcers and blood clots. Much in the same way it works for increasing sexual function, L-arginine cream returns blood circulation in the feet to normal.
More studies are needed to fully determine if the use of L-arginine is useful in preventing ulcers in diabetics or in helping existing ones to heal faster and with fewer complications. Results may be increased if patients also use other preventative measures, such as wearing clothes and shoes that fit and avoiding factors which inhibit proper circulation, such as smoking.
As with any supplement or medication, it is important to discuss the use of L-arginine with a doctor or pharmacist before use. Side effects are uncommon when using the cream version of L-arginine, although oral supplements can occasionally cause diarrhea and stomach pain. If sexual arousal continues for extended periods of time, a doctor should be notified and use of the cream should be discontinued until further notice from a medical professional.
