Ancient healing, modern proof: How traditional remedies are backed by science?
For centuries, healing remedies from ancient Indian traditions have been the foundation of natural health in hundreds of millions of homes. These were not only cultural observances but more substantive systems of healing passed down with meticulous attention to detail. Tired of too many ads? go ad free now As modern science caught up, many of these formerly skeptical rituals and plants are now gaining world-wide acclaim for their incredible contributions to health. One of the key systems that maintained and advanced this knowledge is . The basic texts of Ayurveda, such as the Charaka Samhita and Sushruta Samhita, provided explicit information on anatomy, diagnosis, and natural medicines — several of which are still useful even today. Although modern medicine developed independently, it now is returning to discover what these texts recorded thousands of years ago. Nature's power, sanctioned by science Consider turmeric ("Haldi"), for instance. Beloved in Indian kitchens and healing practices both, turmeric was previously used to dress wounds, eaten during colds, and made part of beauty rituals for the skin. Nowadays, it's been established through research that curcumin, the active ingredient in turmeric, is a strong anti-inflammatory as well as antioxidant. It's being studied for aid in arthritis, Alzheimer's, and even for the prevention of cancer. Another of the old gems, ashwagandha, which in ancient times was called a rasayana or rejuvenator, has made it into clinical trials due to its adaptogenic properties. Recent studies indicate it has the ability to decrease cortisol levels and alleviate stress and anxiety. What was once just a tonic for the weak or old, ashwagandha is now a favorite among young professionals and athletes too, who want mental acuity and toughness. Tired of too many ads? go ad free now Likewise, triphala, a combination of three fruits for digestive wellbeing, has been discovered to possess antioxidant, antimicrobial, and gentle laxative effects. It is now being prescribed by naturopaths and integrative medicine doctors for gut health, detox, and even oral health. Even procedures such as oil pulling, previously a common morning practice in Indian families, are experiencing a comeback. Current dental research verifies its capacity to limit dangerous oral bacteria and foster healthy gums. Bridging the gap The renewed interest in such remedies is no coincidence. Places such as Patanjali Ayurved, which are based on ancient Ayurvedic texts, have popularized old solutions in usable, contemporary packages. They are not inventors, but revivalists — redoing old remedies to accommodate modern lifestyles without losing the authenticity. But it is only when such practices are approved by worldwide scientific communities that real credibility is achieved. Double-blind placebo-controlled trials, phytochemical research, and clinical research articles are lending new life to medicines previously word-of-mouth transmitted. This reconciliation of ancient knowledge and new science is not an either-or process, but an appreciation of their synergy. Brahmi, which has long been blessed for improving memory and intellect, is now researched for its neuroprotective effects. Guggul, a long-time remedy for arthritis and cholesterol, has proven effective in controlling lipid profiles. And neem, a simple garden tree no more, is now a world skincare and dental hygiene ingredient, due to its antibacterial effects. Most are resorting to these traditional remedies after trying everything else. Saloni Pathak, 21, testifies: "I suffered from chronic bloating and exhaustion for more than two years. After exhausting every avenue from elimination diets to supplements, I started adding triphala and ashwagandha into a simple morning routine. Within a few weeks, I felt lighter, clearer, and more attuned to my body. It was as if ancient wisdom had finally caught up with modern life." The increasing popularity of ancient remedies among physicians and the general population implies that the world is no longer viewing tradition as superstition. Rather, it is being rediscovered as a precious guide that contemporary science is just starting to appreciate. Perhaps the future of wellness is not an either-or between the lab and the ashram, but a walk between the two.

Toothpaste & balms can affect brain health: Doctors
1 2 3 4 Nagpur: In a shocking link between everyday hygiene products and neurological health, doctors and neuroscientists raised fresh concerns about ingredients commonly found in toothpaste, balms, and essential oil-based products that may silently impact the brain over time. Observations made during World Brain Week prompted researchers to highlight the potential neurotoxic effects of substances such as camphor, menthol, and eucalyptus — common components found in daily-use products. Experts suggest checking labels and avoiding the overuse of strong aromatic products. "Many of these ingredients can cross the blood–brain barrier via the buccal mucosa, bypassing liver metabolism," said Dr Thomas Mathew, vice dean at St John's Medical College, Bengaluru. "Repeated exposure, especially every 24 to 48 hours, can lead to a phenomenon called chemical kindling, where brain neurons become hyperexcitable, possibly triggering seizures, migraines, or other neuropsychiatric disorders," Mathew said. Patients with unexplained headaches, seizures, anxiety, and even depression showed improvement simply by switching their toothpaste or stopping the use of certain balms, revealed Padma Shri Dr Chandrashekhar Meshram, trustee of the World Federation of Neurology. "These are not allergic reactions but neurostimulation effects. We've seen cluster headaches and migraines vanish within days of stopping using particular brands," he added. A landmark case series published recently in The International Journal of Head and Face Pain also documented cluster headaches linked to toothpaste use, which resolved upon discontinuation of a particular brand. Experimental studies in zebrafish showed that even brief exposure to toothpaste triggered aggression, anxiety, and hyperactivity, suggesting potential impact on the brain. "The concern is not that these products affect everyone, but that they could be contributing to unexplained neurological symptoms in susceptible individuals," said Dr Meshram. "We need collaborative research and funding to explore safe alternatives like water or saline-based oral hygiene products." The spotlight also fell on oral health as a window to brain health. New studies linked gum disease and poor dental hygiene with higher risks of Alzheimer's, Parkinson's, and even stroke. "Regular flossing was associated with up to 22% reduction in ischemic stroke risk," noted Dr S Sen, a researcher from the US. As evidence grows, neurologists are urging both the public and policymakers to consider the hidden neuro-health impacts of seemingly benign daily products, and to explore safer, inert alternatives. THE BRAIN & BALM CONNECTION Common balms and hair oils may contain brain-stimulating chemicals Some toothpaste ingredients can trigger headaches, seizures, and anxiety A zebrafish study showed toothpaste exposure causes hyperactivity and aggression Oral health and gum disease may increase the risk of stroke and Alzheimer's Experts urge consumers to check labels and avoid the overuse of strong aromatic products

Understanding frontotemporal dementia, the disease Bruce Willis is battling
When Hollywood icon Bruce Willis was diagnosed with Frontotemporal Dementia (FTD), it wasn't just another celebrity health update it was a moment of global heartbreak. For decades, Willis played characters who defied odds, cracked jokes under pressure, and carried the weight of the world with a smirk. To imagine him now struggling to find words or understand emotions feels deeply personal for many beyond the emotional impact lies a serious medical reality: FTD is one of the most common causes of early-onset dementia, yet it remains widely misunderstood, frequently misdiagnosed, and largely IS FRONTOTEMPORAL DEMENTIA?Frontotemporal Dementia is an umbrella term for a group of neurodegenerative disorders that primarily affect the frontal and temporal lobes of the brain, regions responsible for personality, language, decision-making, behavior, and emotional regulation. Unlike Alzheimer's disease, which initially presents with memory loss, FTD often begins with changes in personality or language abilities. "While Alzheimer's typically causes memory problems, FTD starts with behavior, mood, or speech issues," says Dr. Sonia Lal Gupta, a senior neurologist. "It affects the part of the brain that makes us who we are how we interact socially, empathize, or express ourselves."Dr. Lal Gupta emphasizes that early signs can be subtle. 'Many families dismiss it as stress, depression, or a midlife crisis,' she says. 'But when someone begins behaving out of character, becomes socially inappropriate, or has trouble with language, it's time to consider a neurological evaluation.' TYPES OF FTDThere are several clinical subtypes of FTD, with overlapping symptoms:1. Behavioral variant FTD (bvFTD):Most common form; marked by changes in behavior, disinhibition, apathy, and lack of empathy.2. Primary Progressive Aphasia (PPA):Involves a gradual loss of language skills-difficulty naming objects, forming sentences, or understanding conversations.3. FTD with motor neuron disease (like ALS):In some cases, FTD co-occurs with movement disorders, including Parkinsonism or CAUSES FTD?FTD is caused by progressive nerve cell loss in the frontal and/or temporal lobes. This shrinkage leads to the loss of function in those regions. It's often sporadic, but up to 40% of cases have a genetic link, caused by mutations in specific genes like MAPT, GRN, or is not linked to lifestyle factors like smoking or poor diet, and currently, there is no cure or disease-modifying treatment. Most treatments aim to manage symptoms and improve quality of life.'Public figures sharing their diagnosis helps remove the stigma,' says Dr. Arvind Iyer, a senior neuropsychiatrist in Mumbai. 'FTD is not just 'getting old'—it's a serious condition that needs timely intervention. The more we talk about it, the earlier we can catch it, and potentially improve quality of life.'WHO DOES IT AFFECT?FTD primarily strikes people between 40 and 65 years of age, though it can appear later. This makes it especially devastating, as it often affects people at the peak of their careers and family life."FTD is under-recognized because we don't expect dementia in people in their 40s or 50s," explains Dr. Arvind Iyer, a neuropsychiatrist. "In many cases, patients are misdiagnosed with depression, bipolar disorder, or even burnout before FTD is considered."KEY SYMPTOMS TO LOOK OUT FORadvertisementEarly behavioral symptoms may include:Loss of social tact or empathyInappropriate jokes or impulsive behaviorApathy or lack of motivationObsessive or repetitive behaviorsPoor personal hygieneChanges in eating habits (e.g., overeating or preference for sweets)In language-dominant FTD:Difficulty forming words (non-fluent aphasia)Trouble understanding or remembering namesLoss of vocabularySpeaking in short, broken sentencesAs the disease progresses, symptoms may overlap with those of Alzheimer's or Parkinson's disease, making accurate diagnosis WHY EARLY RECOGNITION MATTERSCurrently, there is no single test for FTD. Diagnosis typically involves:Detailed neurological and neuropsychological evaluationsMRI or PET scans to detect brain atrophy or hypometabolismGenetic testing, especially for those with a family historyEarly diagnosis is essential to plan care, manage behavioral symptoms, and ensure the family receives support.A CAREGIVER'S REALITYCaring for someone with FTD is uniquely challenging. Patients may no longer express affection, recognize inappropriate behavior, or be able to communicate emotionally draining," shares Renu Verma, whose 68-year-old father was diagnosed with behavioral variant FTD. "He began hiding food, swearing at people, and ignoring family members. It felt like we were watching his personality melt away.""You mourn someone who's still alive," says Rajeev Sharma, caring for his older sister. "She can't follow a conversation. Her eyes are blank, but she's there. That's the hardest part."CURRENT TREATMENT OPTIONSThere is no cure for FTD, but several treatments help manage symptoms:SSRIs (antidepressants) may help with mood swings or compulsive and language therapy for those with language therapy to help with daily and support groups for families and are also exploring disease-modifying drugs, genetic therapies, and clinical trials, but progress is still in early SILVER LINING: AWARENESS IS GROWINGBruce Willis's diagnosis has cast a much-needed spotlight on FTD. It reminds us that dementia is not just an "old age" issue it can strike early, steal identity, and leave families devastated. "Public awareness is essential. FTD is often ignored in the larger dementia conversation," says Dr. Gupta. "We need more training for doctors, more resources for families, and more research funding."advertisementFrontotemporal Dementia is a thief of personality, language, and connection. But awareness, empathy, and timely care can soften the blow. Bruce Willis may have stepped away from acting, but his real-life battle is teaching us something far more powerful: the importance of recognizing the invisible battles so many families are quietly your loved one is showing unusual behavior, personality shifts, or language struggles don't wait. Talk to a neurologist. Early help can make a lifetime of difference.- EndsTrending Reel
