"Cirsoid" means resembling a varix. They are most common on the head or neck.Cirsoid aneurysms appear as nodules or papules.

White grubs and aphids are the major insect pests. The flower spikes turn reddish brown at ripening, the lower leaves dry and the upper leaves yellow. The crop is harvested in the morning after the dew is gone to minimize shattering and field losses. In India, mature plants are cut 15 cm above the ground and then bound, left for a few days to dry, thrashed, and winnowed. Harvested seed must be dried to below 12% moisture to allow for cleaning, milling, and storage. Seed stored for future crops has shown a significant loss in viability after 2 years in storage. Commercial history
Metamucil
Introduced in 1934 by G. D. Searle & Company, Metamucil was acquired by Procter & Gamble in 1985. The name is a combination of the Greek word for change (meta) and the class of fiber that it utilizes (mucilage). In its early years, Metamucil achieved sporadic drug-store distribution as a "behind the counter" product - sold in pharmacies but not on the shelf, so that the pharmacist may counsel the purchaser on correct usage. Since 1974, the brand was also marketed to consumers by print and TV advertising and became available in food outlets. Flavored versions were added in 1979. The brand is sold as powdered drink mixes, capsules and wafers in a variety of flavors. Metamucil contains psyllium seed husks as the active ingredient. It is manufactured in Phoenix, Arizona, by Procter & Gamble. When first marketed to consumers in 1974, Metamucil was marketed as a laxative.
