Klaus Linde (born 1960 in Munich) is a German physician and alternative medicine researcher. He works at the Centre for Complementary Medicine Research at the Technical University of Munich in Germany.
Linde received his MD from Ludwig Maximilian University of Munich in 1990 and his PhD in epidemiology from the Humboldt University of Berlin in 2002. Since 1998 he has been the deputy director of the Centre for Complementary Medicine Research at the Technical University of Munich. [1]
He is known for his research into the effectiveness of St. John's wort, which has found that it is as effective as Prozac for treating major depression, [2] [3] [4] and that German trials of the herb tend to be more positive than do trials from other countries. [5]
He is also known for his studies of the effectiveness of acupuncture. [6] [7] [8] A 2005 study by Linde, for example, found that real acupuncture was no more effective in the treatment of migraines than sham acupuncture, [8] but that both were more effective than no treatment. [9] [10] He has also authored multiple Cochrane reviews on the effectiveness of acupuncture with similar conclusions. [11]
He has also published several papers about the effectiveness of homeopathy. These include a well-known 1997 meta-analysis which found an odds ratio of 2.45 in favor of homeopathy over placebo. However, this review also concluded that there was insufficient evidence that homeopathy was clearly effective for any single condition. [12] [13] A subsequent study by Linde et al. re-examined the data from his 1997 meta-analysis and found that higher quality trials of homeopathy tended to find that homeopathy was ineffective. [14] [13]
Alternative medicine is any practice that aims to achieve the healing effects of medicine despite lacking biological plausibility, testability, repeatability or evidence of effectiveness. Unlike modern medicine, which employs the scientific method to test plausible therapies by way of responsible and ethical clinical trials, producing repeatable evidence of either effect or of no effect, alternative therapies reside outside of mainstream medicine and do not originate from using the scientific method, but instead rely on testimonials, anecdotes, religion, tradition, superstition, belief in supernatural "energies", pseudoscience, errors in reasoning, propaganda, fraud, or other unscientific sources. Frequently used terms for relevant practices are New Age medicine, pseudo-medicine, unorthodox medicine, holistic medicine, fringe medicine, and unconventional medicine, with little distinction from quackery.
Antidepressants are a class of medications used to treat major depressive disorder, anxiety disorders, chronic pain, and addiction.
Homeopathy or homoeopathy is a pseudoscientific system of alternative medicine. It was conceived in 1796 by the German physician Samuel Hahnemann. Its practitioners, called homeopaths or homeopathic physicians, believe that a substance that causes symptoms of a disease in healthy people can cure similar symptoms in sick people; this doctrine is called similia similibus curentur, or "like cures like". Homeopathic preparations are termed remedies and are made using homeopathic dilution. In this process, the selected substance is repeatedly diluted until the final product is chemically indistinguishable from the diluent. Often not even a single molecule of the original substance can be expected to remain in the product. Between each dilution homeopaths may hit and/or shake the product, claiming this makes the diluent "remember" the original substance after its removal. Practitioners claim that such preparations, upon oral intake, can treat or cure disease.
Headache, also known as cephalalgia, is the symptom of pain in the face, head, or neck. It can occur as a migraine, tension-type headache, or cluster headache. There is an increased risk of depression in those with severe headaches.
A placebo is a substance or treatment which is designed to have no therapeutic value. Common placebos include inert tablets, inert injections, sham surgery, and other procedures.
In a blind or blinded experiment, information which may influence the participants of the experiment is withheld until after the experiment is complete. Good blinding can reduce or eliminate experimental biases that arise from a participants' expectations, observer's effect on the participants, observer bias, confirmation bias, and other sources. A blind can be imposed on any participant of an experiment, including subjects, researchers, technicians, data analysts, and evaluators. In some cases, while blinding would be useful, it is impossible or unethical. For example, it is not possible to blind a patient to their treatment in a physical therapy intervention. A good clinical protocol ensures that blinding is as effective as possible within ethical and practical constraints.
Smoking cessation, usually called quitting smoking or stopping smoking, is the process of discontinuing tobacco smoking. Tobacco smoke contains nicotine, which is addictive and can cause dependence. As a result, nicotine withdrawal often makes the process of quitting difficult.
Tension headache, stress headache, or tension-type headache (TTH), is the most common type of primary headache. The pain usually radiates from the lower back of the head, the neck, the eyes, or other muscle groups in the body typically affecting both sides of the head. Tension-type headaches account for nearly 90% of all headaches.
Sumatriptan, sold under the brand name Imitrex among others, is a medication used to treat migraine headaches and cluster headaches. It is taken orally, intranasally, or by subcutaneous injection. Therapeutic effects generally occur within three hours.
Triptans are a family of tryptamine-based drugs used as abortive medication in the treatment of migraines and cluster headaches. This drug class was first commercially introduced in the 1990s. While effective at treating individual headaches, they do not provide preventive treatment and are not considered a cure. They are not effective for the treatment of tension–type headache, except in persons who also experience migraines. Triptans do not relieve other kinds of pain.
Varenicline, sold under the brand names Chantix and Champix among others, is a medication used for smoking cessation and for the treatment of dry eye syndrome. It is a nicotinic acetylcholine receptor partial agonist. When activated, this receptor releases dopamine in the nucleus accumbens, the brain's reward center, thereby reducing cravings and withdrawal symptoms with smoking cessation, although less pronounced than a full agonist.
Antimigraine drugs are medications intended to reduce the effects or intensity of migraine headache. They include drugs for the treatment of acute migraine symptoms as well as drugs for the prevention of migraine attacks.
In homeopathy, arsenicum album (Arsenic. alb.) is a solution prepared by diluting aqueous arsenic trioxide generally until there is little amounts of Arsenic remaining in individual doses. It is used by homeopaths to treat a range of symptoms that include digestive disorders and, as an application of the Law of Similars, has been suggested by homeopathy as a treatment for arsenic poisoning. Since the arsenic oxide in a homeopathic preparation is normally non-existent, it is considered generally safe, although cases of arsenic poisoning from poorly prepared homeopathic treatments sold in India have been reported. When properly prepared, however, the extreme dilutions, typically to at least 1 in 1024, or 12C in homeopathic notation, mean that a pill would not contain even a molecule of the original arsenic used. While Anisur Khuda-Bukhsh's unblinded studies have claimed an effect on reducing arsenic toxicity, they do not recommend its large-scale use, and studies of homeopathic remedies have been shown to generally have problems that prevent them from being considered unambiguous evidence. There is no known mechanism for how arsenicum album could remove arsenic from a body, and there is insufficient evidence for it to be considered effective medicine (for any condition) by the scientific community.
Management of depression is the treatment of depression that may involve a number of different therapies: medications, behavior therapy, psychotherapy, and medical devices.
Trick or Treatment? Alternative Medicine on Trial is a 2008 book by Simon Singh and Edzard Ernst. The book evaluates the scientific evidence for alternative medicines such as acupuncture, homeopathy, herbal medicine, and chiropractic, and briefly covers 36 other treatments. It finds that the scientific evidence for these alternative treatments is generally lacking. The authors concluded that homeopathy is merely a placebo.
Preventive treatment of migraine can be an important component of migraine management. The goals of preventive therapy are to reduce the frequency, painfulness, and/or duration of migraine attacks, and to increase the effectiveness of abortive therapy. Another reason to pursue prevention is to avoid medication overuse headache (MOH), otherwise known as rebound headache, which can arise from overuse of pain medications, and can result in chronic daily headache. Preventive treatments of migraine include medications, nutritional supplements, lifestyle alterations, and surgery. Prevention is recommended in those who have headaches more than two days a week, cannot tolerate the medications used to treat acute attacks, or those with severe attacks that are not easily controlled.
The German acupuncture trials were a series of nationwide acupuncture trials set up in 2001 and published in 2006 on behalf of several German statutory health insurance companies because of a dispute as to the usefulness of acupuncture. They consisted of one observational study on acupuncture side effects, and four randomized controlled trials (RCTs) investigating acupuncture treatment for low back pain, knee osteoarthritis, migraine prophylaxis, and tension-type headache. The trials are considered to be one of the largest clinical studies in the field of acupuncture.
Migraine may be treated either prophylactically (preventive) or abortively (rescue) for acute attacks. Migraine is a complex condition; there are various preventive treatments which disrupt different links in the chain of events that occur during a migraine attack. Rescue treatments also target and disrupt different processes occurring during migraine.

The infinitesimally low concentration of homeopathic preparations, which often lack even a single molecule of the diluted substance, has been the basis of questions about the effects of the preparations since the 19th century. Modern advocates of homeopathy have proposed a concept of "water memory", according to which water "remembers" the substances mixed in it, and transmits the effect of those substances when consumed. This concept is inconsistent with the current understanding of matter, and water memory has never been demonstrated to exist, in terms of any detectable effect, biological or otherwise.
