Chaste tree has helped me with my irregular menstrual cycle, sore, swollen breasts, and anxious feelings. It takes 3 months to work, but was effective for a year. I think my body got used to it and I had to take a break. But, I am very happy with Oregon Wild Harvest's quality and freshness of their herbs. I am happy they come in a glass bottle. I wish the bottle came with less, this bottle has 90 pills and I take one a day and I noticed by the third month, the herbs seem like they work less well. And then I get a new bottle and they work again. I'm not sure if it is the freshness of the herb or my body becoming "used" to it. Overall, I love this company and I only buy chaste tree from Oregon Wild Harvest.
