St John’s Wort

Some research shows St John's Wort can help to treat mild to moderate depression.

But for more severe depression, research suggests it doesn’t work as well as antidepressant drugs. It can have side effects in the same way as prescribed antidepressants.

You shouldn’t take St Johns Wort with antidepressants because they may interact. It can also interact with other drugs including:

• the contraceptive pill

• some chemotherapy drugs

• some HIV drugs

• some epilepsy drugs

Talk to your doctor first if you are planning on taking St John's Wort, particularly if you are taking any other medicines. Your doctor can’t prescribe it for you. You have to buy it from health food stores or alternative medicine suppliers.

Ginkgo

Ginkgo is also called ginkgo biloba, fossil tree, maidenhair tree, kew tree, bai guo ye and yinhsing.

Ginkgo has been reported to help people with anxiety, memory loss, stress, sexual problems and asthma.

We know from research that ginkgo can improve blood flow to the brain, so it may help improve mood. But it can cause side effects, including:

• diarrhoea

• headaches

• heart palpitations

• dizziness

There have also been reports of spontaneous bleeding and fits in people who have taken ginkgo. You should not take ginkgo if you are taking drugs to help thin your blood (anticoagulants). These include drugs such as warfarin or aspirin. You shouldn't take it with drugs to stop you from having fits, either.

Other remedies

You may have heard about other remedies, such as S-Adenosyl Methionine (SAM-e) or certain homoeopathic medicines. Some research shows that these can help with depression, but we need more research.

Because their benefits are uncertain, you shouldn't use them instead of antidepressant drugs if you have moderate or severe clinical depression.
