Garlic to Lower High Blood Pressure / Hypertension

Constituent that helps lower high blood pressure: Allicin and production of hydrogen sulphide.

Scientific name: Allium sativum

Part used: cloves

Allicin is volatile and on heating produces various diallyl sulphides, the commonest of which is diallyl disulphide. This chemical helps lower blood pressure by dilating the muscles of blood vessels and keeps the cardiovascular system healthy.

High Blood Pressure/Hypertension - Garlic

Studies evaluating the effectiveness of garlic in lowering blood pressure have provided conflicting results. A systematic review and meta-analysis suggests that garlic supplementation has blood pressure lowering effect especially in individuals with a blood pressure of systolic blood pressure or SBP 140 mm Hg, and diastolic blood pressure or DBP 90 mm Hg. However, another study concluded that garlic powder tablets have no clinically relevant blood pressure lowering effects in middle-aged, normo-lipidemic individuals.

So, it is actually up to you to use or not to use garlic to reduce high blood pressure. Fresh crushed garlic has the best effect but if you can't stand the pungent smell of garlic, you can use supplements that come in the form of capsules or pearls.

Dose: Daily dose of garlic supplement for up to five months.

Side effects:

► Although garlic is well tolerated by most people, it may cause stomach irritation in sensitive individuals.

► Nursing mothers need to be cautious since garlic in breast milk may cause colic in infants.

► Consult your doctor before taking garlic supplements if you are on blood sugar medication or on NSAIDs.

i want to take sarpagandha for BP but side effect after stoping it are looking bad pl. advise me. HARPAL SINGH 9779153011

The write up gives information with scientific explaination for stated claims . It would be great to see some light thrown on 1. Can the 'snakeplant root ' be taken by patients who take other allopathic medicines such as Amlong , Tenalol, Losartan , olmezest etc safely .2] Whether the effect of the Indian Snakeroot powder is only temporary or does it cure the problem from the roots as Ayurvedic doctors claim Ayurved does ?
