Sadabahar: Uses, Benefits, Side effects and More By Dr. Rajeev Singh

By Dr Rajeev Singh +2 more


Sadabahar or sadaphuli is a small shrub bearing purple, pink, or white flowers throughout the year and hence called “Sadabahar.” Natively called “periwinkle” in English, Catharanthus roseus originated in Madagascar. This ornamental plant is cultivated throughout tropical and subtropical areas. Nearly 12 species are identified, out of which two are popular ground covers (a plant that grows over an area of ground). All the species bear single flowers and have opposite leaves. When the flowers are plucked, they exude a milky juice. The flowers bloom in March or April. Alba variety has white flowers, Atropurpurea has purple flowers, and Alboplena bears white flowers. Periwinkle is a rich source of medicinal compounds, and you need to know how nature has encapsulated love and care for all of us with this amazingly beautiful plant. Let us read more about the various health benefits Sadabahar leaves has to offer.1

The Sadabahar plant might act as a “diuretic.” Taking Sadabahar might make the body less effective at eliminating lithium. Lithium levels may rise as a result, which may have various side effects. I suggest if you are on lithium, see your doctor before consuming Sadabahar in any form. You might need to adjust your lithium dosage.

Dr. Siddharth Gupta, MD

  • Sadabahar plant has been used in traditional medicine to treat various ailments, including malaria and diabetes. [source: pubmed.ncbi.nlm.nih.gov]
  • Catharanthus roseus has shown potential in the treatment of neurodegenerative diseases like Alzheimer’s and Parkinson’s. [source: pubmed.ncbi.nlm.nih.gov]

Potential Uses of Sadabahar for Overall Health: 

Some of the potential benefits of Sadabahar are described as under:  

Potential Uses of Sadabahar on Type-2 Diabetes 

Type-2 diabetes is a metabolic disorder characterized by derangements (abnormalities) in blood glucose levels, due to decreased insulin (a hormone that regulates blood glucose) response or insulin resistance. Nammi et al. conducted a study in 2003 to assess the effects of sadabahar leaf juice on diabetic rats. The findings of this study stated that sadabahar had an anti-diabetic effect, attributed to increased secretion of insulin from beta cells of the pancreas. This indicates that sadabahar leaves may help in managing diabetes. However, we need more studies to support these claims in humans.3 

Potential Uses of Sadabahar on Hypertension 

Hypertension is defined as systolic blood pressure >130 mm Hg and diastolic blood pressure>80 mm Hg. Sadabahar as an anti-hypertensive (causing a decrease in blood pressure) agent has been used in folklore medicine. Ara et al. conducted a study in 2009 in hypertensive rats fed sadabahar leaves extract. The results of this study supported the use of sadabahar to manage high blood pressure, indicating that it may positively impact blood pressure. However, we need more studies to ascertain these claims in humans.4 

Potential Uses of Sadabahar on Cognitive Function 

A literature review by Medina et al. In 2010 stated that sadabahar contains chemical compounds called alkaloids which are known to enhance cognitive function. This effect is attributed to the inhibition of an enzyme called phosphodiesterase enzyme. The inhibition of this enzyme increases the levels of bio-molecules known to regulate memory, learning, etc. This indicates that sadabahar can positively impact cognitive function.5 

Potential Uses of Sadabahar on Male Pattern Hair Loss 

Androgenic Alopecia, or male pattern hair loss in men and female pattern hair loss in women, is a patterned and progressive hair loss. A review by Justin et al. was conducted in 2017, stating sadabahar may help manage androgenic alopecia. However, the exact mechanism behind this is unknown, and we need more scientific studies to claim these effects in humans.6 

Potential Uses of Sadabahar on Cancer 

Vinca alkaloids are medicinal compounds obtained from the Madagascar periwinkle plant or sadabahar. Vinblastine, an important Vinca alkaloid, has anti-tumour activity and is widely used to manage testicular cancers. Vinorelbine, another alkaloid from sadabahar, finds use for managing breast cancers and osteosarcoma (bone cancer cells). This indicates that sadabahar may help manage cancers. However, the potent anticancer Vinca alkaloids are fully processed, and safety and toxicity are tested before use. We do not promote the use of sadabahar flowers or leaves for managing cancers.7

Other Potential Uses of Sadabahar: 

  • Sadabahar has astringent properties and may help soothe the pain of canker sores.8 
  • European herbalists have used periwinkle for managing watery discharge in conditions like bleeding gums and diarrhea.8 
  • The presence of vinpocetine in sadabahar has beneficial effects on hearing loss due to aging (presbyacusis). Additionally, vinpocetine may help in hypercalcemia (increased calcium in the body) which is commonly seen in patients with kidney failure.8 
  • Herbalists have used periwinkle for managing headaches, poor memory and vertigo.9 
  • Consumption of sadabahar leaves can positively impact the skin.9 
  • It may benefit women who experience painful menstrual cramps and menorrhagia (heavy menstruation).9 
  • In India, the juice from the leaves of sadabahar are used to treat wasp stings.10 

Though there are studies that show the benefits of Sadabahar in various conditions, but these are insufficient and there is a need for further studies to establish the true extent of the benefits of Sadabahar on human health.  

Alzheimer’s disease (AD), a neurodegenerative illness of the central nervous system, affects 50–60% of people with dementia. It is distinguished by significant memory loss, emotional instability, and personality changes in later life. Studies have shown that the extracts of Sadabahar may aid in Alzheimer’s Disease as it has the potential to stimulate the nervous system. I suggest the consumption of Sadabahar with a doctor’s guidance and avoiding self-medication at all costs.

Dr. Rajeev Singh, BAMS

How to Use Sadabahar? 

  • To avail of the health benefits, sadabahar leaves are used to make juice and consumed. 
  • The leaves and flower petals of sadabahar are boiled and used to make “Kadha”, a traditional medicinal drink in India. 
  • The fresh leaves of sadabahar are either directly chewed or dried and ground to make a powder which is then consumed.10 

You must consult a qualified doctor before taking any herbal supplements. Do not discontinue or replace an ongoing treatment of modern medicine with an ayurvedic/herbal preparation without consulting a qualified doctor.   

Side Effects of Sadabahar: 

A few side effects related to the consumption of sadabahar include: 

  • Loh et al. in 2008 stated that vincristine, an alkaloid derived from Sadabahar can cause hair loss, constipation, hyponatremia (low sodium levels in the blood) and peripheral neuropathy (nerve damage resulting in weakness, pain, etc).11 
  • An excess consumption of sadabahar leaves or petals can result in unwanted effects like nausea, vomiting, headache and fever.12 

However, if you experience any adverse reactions to Sadabahar, it is advised to discontinue its intake and immediately contact a doctor or your Ayurvedic physician who has prescribed it. They will be able to guide you appropriately for your symptoms. 

Precautions to Take With Sadabahar: 

Consuming Sadabahar is okay if taken in moderate amounts. However, general precautions must be followed in the following conditions: 

  • The safety data regarding the use of sadabahar in pregnant and lactating women, the elderly and children is limited; therefore it is advised to take necessary cautions if you plan to add this herb to your dietary routine. It is advised to consult a doctor for proper advice.11

Interactions with Other Drugs: 

  • Sadabahar is known to cause a reduction in blood pressure, so if you’re on antihypertensive medicines, using sadabahar and your medications can cause your blood pressure to drop too low.  
  • Consumption of sadabahar leaves may help in reducing blood sugar, so if you’re taking your anti-diabetic medications along with this herb (sadabahar), it can result in very low blood glucose levels. 

However, you must always seek the advice of your Ayurvedic physician about the possible interaction of sadabahar with other drugs and follow the prescription thoroughly, as they will know your health condition and other medications you are taking.3,9
