1/5
St. John’s wort: Reduces effectiveness of the pill
This herbal medicine contains natural active anti-depressant effects that stimulate the nervous system and the production of certain neurotransmitters (dopamine, serotonin). Used as a treatment for mild to moderate depression, it is perfect for thwarting big morale drops. However, if you’re on birth control, watch out - St. John's wort decreases and may even completely negate the effects of the contraceptive pill. It can also cause photosensitivity in people with fair skin.
2/5
Valerian: Increased risk of drowsiness
The calming properties of valerian make it a good cure for anxiety and nervous restlessness. It is commonly used as a sleep aid for those prone to insomnia. But beware of drowsy driving! Never operate heavy machinery when you’ve taken valerian. Also, its sedative effects can impact on certain medications such as analgesics, antitussives or antihistamines. Valerian may also interact with anticoagulant treatment and could potentially decrease the absorption of iron supplements.
3/5
Red yeast rice: Possible intolerances
Obtained through the fermentation of yeast on rice, red yeast rice is commonly used in Traditional Chinese Medicine (TCM). It has been said to lower high levels of LDL (bad) cholesterol and maintain blood pressure. However, it is not recommend for you to consume red yeast rice if you are already in the midst of cholesterol-lowering treatment and medication. Also, as the active ingredient in red yeast rice is the same as that used in prescription drugs for high cholesterol, it has all the possible side effects and precautions associated with such drugs.
4/5
Ginkgo & ginseng: Do not mix with anticoagulants
These plants are capable of “boosting” your memory as well as your blood circulation (for example, to cure heavy legs). Increasing your blood circulation could pose a risk of continuous bleeding without clotting when you have taken anticoagulants (including aspirin). If you are already taking supplements rich in omega-3, it is best to seek medical advice.
5/5
Echinacea: Disrupts immunosuppressants
Echinacea boosts immunity, strengthens the body’s defences, prevents viruses (flu, colds) and infections (recurring cystitis). However, its composition and effectiveness can vary greatly according to the extraction process (whether you are taking it in capsule form or as a tincture). One should always seek advice from a healthcare professional before taking echinacea, especially since the use of echinacea is advised against during the treatment of autoimmune diseases (chemotherapy, transplants, etc) and may also cause allergies.

St. John's wort: Reduces effectiveness of the pill

Think using valerian or ginkgo freely will cause no harm? Think again.

From ginkgo to valerian, echinacea to mint, there is no doubt that natural herbal remedies still remain popular to this day, surviving centuries of traditional uses over time. But despite their many virtues, they are not without dangers. Always be sure you know what you’re doing when you consume or use botanicals as an alternative medicine or remedy. You don’t want any unpleasant surprises.
