Fenugreek seeds -
Fenugreek is a herb native to the middle east and India, and legend has it that fenugreek was given to harems as herbal breast enhancers.
The Real Deal: Fenugreek is often used in pills and supplements that claim to increase breast size, however, no clinical trials have been properly conducted to prove or disprove this rumor. There is however some promise... fenugreek seeds contain a compound called diosgenin, which HAS been clinically studied and can become estrogen and progesterone, but there is no mechanism for this to happen in the body, only in a lab. For many women, estrogen increases can stimulate breast tissue increases. So if fenugreek could theoretically increase estrogen in the blood, but it probably doesn't work in the body. Also, fenugreek seeds have undergone limited clinical studies in humans with regards to increasing breast milk production, and they can stimulate production of breast milk.
Dangers: People with a peanut allergy or soy allergy can be allergic to fenugreek. It can also cause diarrhea and gas, and should not be taken by anyone who is diabetic, or taking medication for hypoglycemia.
Dosage: Ok, it is dangerous to exceed 5,000 mg a day, but to experience any potential for breast enlargement, one would take about 3,000 mg a day. This is a fine line between what some say you need, and others say is dangerous. Mind you, this is NOT medical advice, only facts and research based on other peoples recommendations and warning. It is best to spread out the intake of fenugreek over a period of 3 times in a day.
