I have been taking Vitex for two months now and I absolutely love it going through perimenopause. It works really well with Hot flashes not being able to sleep mood swings. It did take about two months for it to start working cause it is a very slow working herb and then I gave my body a break for like two weeks and I could totally tell that my mood swings came back. My hot flashes came back. I was not able to sleep again so I’m glad I let my body take a break, but I’m also ordering it again and getting back on it. I was never happier like when I’ve been taking it

Finishing the bottle

I started taking the Vitex a few years ago and I slacked off a little and now I feel like they are a different color than before. I'm not 100% sure that I am taking the same supplement and I have nothing to compare it too since I finished my other bottles. I am going to finish the bottle I have to see what happens and if I feel better I'll continue with them. In the beginning they definitely helped balanced my hormones and my cramps weren't as bad. Since it has been some months since I have taken them, I'll start them this month.

My coworker recommended them to help with my hot flashes and they are definitely helping. I noticed a difference after a few days of taking them. They're easy to swallow too. I'll be buying another bottle

Acabo de comprarlo por primera vez y espero ver resultados muy pronto. Hasta los momentos no he sentido algo extraño.

This product seems to help regulate, my unregulated cycles! I have tried other products that work, as well. However, the other products are more expensive. This product is of quality for the value!

Questions and answers

What is chaste tree berry?

Chaste tree berry is the dried, ripe fruit of the chaste tree. The Latin name of the plant is Vitex agnus-castus. Other names are chasteberry, vitex and monk's pepper. The plant is a scented shrub or small tree in the mint family.

Where does chaste tree berry come from?

The chaste tree is native to the Mediterranean region and Asia, and it is grown in warm regions. A 2009 World Health Organization text names Albania and Morocco as main sources. The part used is the ripe fruit, which is dried.

What does chaste tree berry look, taste and smell like, and why?

The dried berry is round, very hard and reddish-brown to black, and only 2 to 4 millimeters wide. It has a faint smell and a slightly bitter taste. The smell comes from an oil in the fruit that holds compounds such as cineole and limonene. The leaves of the shrub also give off a scent when they are bruised.

What compounds are in chaste tree berry?

The berry holds a scented oil and three main groups of plant compounds: flavonoids, iridoids and diterpenes. Flavonoids are plant pigments, and the main one here is called casticin. Iridoids and diterpenes belong to the terpenes, compounds that plants build from small repeating units of carbon. Official quality standards, called pharmacopoeias, name casticin and the iridoid agnuside as the compounds to measure in the fruit.

4 more questions about chaste tree berry

What exactly is in our capsule?

Each capsule holds 500 mg of organic chaste tree berry extract, a concentrated form of the dried fruit. In an extract ratio, the first number is the dried plant used and the second is the extract made. So the 4:1 on our label means about 4 parts of dried berry for each 1 part of extract. The other ingredients are rice flour and hypromellose, made from plant fiber (cellulose), which forms the capsule shell.

How is chaste tree berry extract made?

An extract is made by soaking the plant in a liquid such as water or alcohol. The liquid can then be dried to a powder for use in capsules. European standards for chaste tree fruit describe dry extracts made with alcohol and water.

Where does the name come from, and how long has the plant been known?

The name agnus-castus says one thing twice: both halves are old words for chaste or pure. One half is Greek and the other is Latin. The ancient writer Dioscorides already mentioned the plant. Its bendy twigs are used to weave baskets, and its fruits are used as a flavoring.

What do researchers study about chaste tree berry?

Researchers have studied which compounds the fruit holds and how the plant makes them. They have compared chasteberry products from Japan, Europe and the United States to see how they differ. They have also built lab methods to measure these compounds. These are study topics, not claims about our product.
