The Motherwort herb is another medicinal herb that should be avoided by pregnant women or women who are trying to get pregnant as it induces uterine contractions.As easy to grow in your garden as Lavender (it is after all a weed!), Motherwort can easily overtake your garden lock stock and barrel (the weed effect again). The efforts though are fully worth it as you will have an endless supply of Motherwort right on your doorstep.
And if you find that it's simply too much trouble to grow (or cull) the Motherwort, then you always have the option of popping down to your nearest health store where you can find it in the form of teas (that's handy isn't it?), capsules, extracts and pills. Only remember that taking too much Motherwort can cause diarrhea so follow dosage instructions carefully.
