Garlic (Allium sativum) is a bulbous plant from the onion family which is widely used as food seasoning. It has also been used as a traditional medicine. Garlic is sometimes recommended for cancer prevention based on observational population studies assessing garlic intake and risk of cancer and on studies indicating beneficial effects on processes such as activation of carcinogenic substances, cell proliferation and apoptosis (cell death).

Progressive Muscle Relaxation (PMR) therapy involves sequential tensing and relaxation of major skeletal muscle groups and aims to reduce feelings of tension, to lower perceived stress, and to induce relaxation. PMR is purported to decrease the arousal of the autonomic and central nervous system and to increase parasympathetic activity. Two systematic reviews (SRs) published since 2019 are included in this summary. One included 12 randomised controlled trials (RCTs) with 1147 participants and assessed a range of outcomes, the other one investigated PMR for preventing and alleviating chemotherapy-induced nausea and vomiting and included six RCTs with 288 participants. An additional 25 randomised and non-randomized controlled clinical trials (RCTs and CCTs) were also reviewed for this summary.

The Budwig diet consists of a special lacto-vegetarian regimen that focuses on a particular blend of oil and protein, i.e. flaxseed oil and cottage cheese or quark. The general guidelines of the diet emphasise foods in their natural state, plenty of fat in the form of cold-pressed flaxseed oil and a spreadable fat based on flaxseed oil, and protein in the form of quark or cottage cheese. Freshly pressed juices and herbal teas are also an integral part. Dr Johanna Budwig (1908-2003), a licensed pharmacist, stated that consuming processed fats was the primary cause of the majority of diseases, most notably cancer. According to her theory, combining polyunsaturated fatty acids derived from flaxseed with sulfhydryl-containing proteins from cottage cheese or quark has an effect on the growth and progression of malignant tumours.
