There are many forms of birth control, many of which are hormonal-based. If you fear the side effects that come with hormonal contraception, herbal birth control may be a good option.

While some herbs promote fertility, others may have a hindering effect on it. That’s why many herbs can be used for contraceptive purposes.

Some prevent the fertilised egg from implanting in the uterus while others induce uterine contractions. Some even result in sterility.

Herbs that promote temporary sterility

• Stoneseed Root is used by tribeswomen in Dakota, who soak the root in cold water for hours, then consume it daily for six months to prevent pregnancy.

• Jack-In-The-Pulpit Root is used in a similar way by the Hopi tribeswomen.

• Thistle is boiled in water by the Quinault tribeswomen to make a tea that is thought to promote temporary sterility.

Herbs that prevent implantation

• Queen Anne’s Lace, or Wild Carrot Seed, is a form of herbal contraception that originates in India. After unprotected sex, the woman should consume these seeds for seven days to prevent implantation.

• Smartweed Leaves are believed to prevent implantation thanks to its high content of rutin, quercetin, and gallic acid.

Side effects of herbal birth control

Herbs have both medicinal power and side effects. The most common include:

• Stomach upsets

• Fatigue

• Allergic reactions

• Low-blood pressure

• Excessive sedation or depression (possibly resulting from interaction with other drugs)

• Increased photosensitivity (possibly resulting from interaction with other drugs)

• Kidney irritation and inflammation

• Enhanced sedative effects of other supplements

Different herbs may cause different side effects. Also, different individuals react differently to herbs.

It’s important to talk to your doctor before taking any herbal supplements and strictly follow the directions (on the label or from your doctor) to avoid side effects.

Keep track of your symptoms in case you need to discuss it with your doctor. You need to be extra careful when using herbs because herbal supplements are not regulated by the authorities like other medications are.

Risks associated with herbal birth control

If you are taking any medication (either prescription or over-the-counter), you must talk with your doctor first to avoid drug interactions.

You must also bear in mind that you could very well still get pregnant while taking herbal contraception. If that happens, stop using the herbs immediately and seek medical help as some herbs may be harmful to a developing foetus.

If you are taking an herbal supplement and require surgery for a medical condition, inform your doctor since some herbs may interact with the anaesthesia.
