| Aloe vera — a medicinal succulent (Aloe barbadensis Miller) used as a complex botanical mixture whose clinically used preparations typically derive from (i) the inner leaf gel (polysaccharide-rich) and/or (ii) whole-leaf extracts containing anthraquinones. It is best classified as a botanical/natural product mixture (not a single agent). Common abbreviations include AV (Aloe vera). Key bioactives often discussed in oncology-adjacent literature include polysaccharides such as acemannan (immunomodulatory/wound-healing biomaterial profile) and anthraquinones such as aloe-emodin/emodin/aloin (more directly cytotoxic in vitro, but also linked to GI toxicity/carcinogenic hazard signals in certain whole-leaf preparations). Primary mechanisms (ranked):
Bioavailability / PK relevance: Aloe preparations are heterogeneous. High–molecular-weight gel polysaccharides (e.g., acemannan) have limited systemic bioavailability and are most relevant for local mucosal/skin exposure or immune-adjacent effects; anthraquinones are more systemically absorbable but undergo metabolism and are constrained by GI tolerance and safety concerns. “Decolorized/low-anthraquinone” products differ materially from nondecolorized whole-leaf extracts. In-vitro vs systemic exposure relevance: Many reported anticancer effects use crude extracts or isolated anthraquinones at concentrations that may exceed typical achievable systemic levels from oral supplements; supportive-care benefits (skin/mucosa) are more plausibly local exposure–driven. Clinical evidence status: Predominantly preclinical for direct anticancer activity. Human evidence is mainly supportive-care (e.g., radiation dermatitis and oral mucositis), with mixed RCT outcomes and heterogeneous formulations; there is no high-quality evidence establishing Aloe vera as a primary anticancer therapy. Aloe vera Therapeutic properties include: anti-microbial, anti-viral, anti-cancer, anti-oxidant, anti-inflammatory, skin protection, wound healing, and regulation of blood glucose and cholesterol.active constituents, such as aloe-emodin and acemannan. • Aloe vera extracts harbor antioxidant compounds that can scavenge free radicals, protecting cells from oxidative damage—a factor in aging and cancer development. Aloe vera’s blend of bioactive compounds offers a range of biological activities—including anti-inflammatory, antioxidant, immunomodulatory, and wound-healing effects—that have attracted interest for complementary roles in health maintenance and cancer supportive care. While it is not a primary anticancer agent, its potential to mitigate treatment side effects, enhance immune responses, and possibly contribute to chemoprevention makes it a subject of ongoing research.

| Destruction of mitochondrial transmembrane potential, which is widely regarded as one of the earliest events in the process of cell apoptosis. Mitochondria are organelles within eukaryotic cells that produce adenosine triphosphate (ATP), the main energy molecule used by the cell. For this reason, the mitochondrion is sometimes referred to as “the powerhouse of the cell”. Mitochondria produce ATP through process of cellular respiration—specifically, aerobic respiration, which requires oxygen. The citric acid cycle, or Krebs cycle, takes place in the mitochondria. The mitochondrial membrane potential is widely used in assessing mitochondrial function as it relates to the mitochondrial capacity of ATP generation by oxidative phosphorylation. The mitochondrial membrane potential is a reliable indicator of mitochondrial health. In cancer cells, ΔΨm is often decreased, which can lead to changes in cellular metabolism, increased glycolysis, increased reactive oxygen species (ROS) production, and altered cell death pathways. The membrane of malignant mitochondria is hyperpolarized (−220 mV) in comparison to their healthy counterparts (−160 mV), which facilitates the penetration of positively charged molecules to the cancer cells mitochondria. The MMP is a critical indicator of mitochondrial function, directly reflecting the organelle's capacity to generate ATP through oxidative phosphorylation. |
